Description

Method, device and system for positioning web page elements

Technical Field

The present application relates to the field of internet technologies, and in particular, to a method for positioning web page elements, an apparatus for positioning web page elements, and a system for positioning web page elements.

Background

In the software development process, software testing is indispensable. The software test utilizes a test tool to carry out test operation according to a certain test scheme and flow, thereby achieving the purposes of discovering defects hidden in the software, reducing the cost of software development and maintenance and promoting the software quality to be improved. The cost of software testing accounts for 30% -50% of the whole software development process, and with the continuous improvement of the functional complexity of software, the corresponding automatic testing technology is continuously developed and advanced.

Among various types of automated tests, the test closest to the user requirement is the automated test of a User Interface (UI) related to user interaction, and writing a UI automated test script of a web page inevitably encounters a web page element identification problem. The positioning operation for the web page element is not only reflected in the operation process of the service flow, but also reflected in other aspects, such as content inspection of the web page text element, attribute inspection of the web page element, use of the attribute value of the web page element as a variable, inspection of complex web page elements, such as < table > sub web page elements, and the like. Since the automated testing of the UI is closest to the user's needs, the maintenance cost of the positioning information data of the web page elements also becomes an indispensable cost in the UI automation script maintenance process.

At present, the positioning mode of web page elements is based on a static mode, namely once a certain type of positioning mode is used, the actual positioning information is determined, and the positioning information cannot be automatically checked and repaired. For example, in the stage of writing the UI automation test script, the information that is found on the web page and can uniquely identify the web page element is recorded as the positioning information of the web page element, and in the subsequent test, the content is the content that needs to be mainly maintained in the UI automation test script. Often, the way to locate web page elements is also unique, for example, if id attributes are used to locate web page elements, manual correction is required once the id attributes change, and thus web page elements cannot be located efficiently and simply.

Therefore, one of the problems to be solved by those skilled in the art is to provide a method, an apparatus and a system for positioning web page elements, so as to quickly position web page elements, improve the execution efficiency of positioning web page elements, and enable automatic repair of positioning information of web page elements, thereby ensuring the adaptivity of positioning information of web page elements to the maximum extent and effectively reducing the maintenance cost of positioning information of web page elements.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.

One of the core ideas of the embodiment of the application is that the positioning information with the highest priority is determined by recording the multi-dimensional positioning information with the priority of the web page to be detected, the optimal positioning information is automatically repaired, and accuracy guarantee is provided for the positioning information with the highest priority, so that the adaptivity of the web page element positioning information is guaranteed to the maximum extent on the whole, and the maintenance cost of the web page element positioning information is reduced to the maximum extent.

Referring to fig. 1, a flowchart illustrating steps of embodiment 1 of a method for positioning web page elements according to the present application is shown, where the method specifically includes the following steps:

step 101, acquiring at least two pieces of positioning information of one or more web page elements in a web page to be detected;

as an example of specific application of the embodiment of the present application, reference may be made to a schematic diagram of multi-dimensional positioning information of a web page element (element) in the present application shown in fig. 2, where the positioning information of the web page element in step 101 may include three, specifically:

r1: first positioning information formed by attribute combination of the web page elements;

r2: second positioning information formed by attribute combinations of parent class elements of the web page elements and relative positions of the web page elements in the parent class elements thereof;

r3: third positioning information formed by an XPATH path of the web page element.

Referring to the flow chart of the multi-dimensional positioning information processing of a web page element of the present application shown in fig. 3, in a preferred embodiment of the present application, the step 101 may include the following sub-steps:

for example, the web page to be tested includes 30 controls (a control is one of the web page elements), and the attribute information "tagName": INPUT "," name ": user", "type": text "," value ": and/or corresponding to a certain web page element can be obtained.

Preferably, the attribute information may include an attribute name and a corresponding attribute value, and before the sub-step of determining whether the attribute information uniquely locatable to the corresponding web page element exists, that is, before the sub-step S2, the method may further include:

and a substep S11, filtering out attribute information with an attribute value being null from the attribute information corresponding to the web page element.

Assume that there are several attribute names as follows: tagName, nodeName, src, title, and the corresponding attribute values are:

"tagName":"A"

"nodeName":"B"

"src":"/xxx/yy.html"

"title":""

since the attribute name whose attribute value is null does not contribute to the positioning of the web page element, the attribute information whose attribute value is null can be filtered, for example, "title": since its attribute value is "null", and it is filtered because it is a null value.

for example, assuming that attribute information "tagName": INPUT "," name ": user", "type": text "corresponding to a certain web page element can be uniquely located to the attribute information of the corresponding web page element, the above attribute information is recorded to form an attribute combination {" tagName ": INPUT", "name": user "," type ": text", "of the web page element itself as the first location information R1.

in the embodiment of the application, the step of obtaining the attribute combination of the parent class element of the web page element is the same as the step of obtaining the attribute combination of the web page element.

Assuming that the attribute combination of the parent element of the web page element is { "tagName": form "and" index ": 1" }, if the web page element is arranged at the first bit of the parent element, the relative position information may be recorded as "index": 1", and the attribute combination and the relative position information of the parent element are recorded as { parent {" tagName ": form" "index": 1"}" tagName ": INPUT", "index": 1"}, which is used as the second positioning information R2

In addition, if the parent element of the web page element cannot be uniquely located, the parent element may be used as the current web page element, the parent element of the current web page element is acquired, and the substep S4 of acquiring the attribute information of the corresponding parent element is executed again.

In practical applications, the execution sequence of the sub-step S7 is not limited, for example, the sub-step S7 may be performed before the sub-step S1 is executed, or after all the sub-steps are completed, or may be performed simultaneously with other sub-steps, which is not limited in this application.

For the web page element, an XPATH path positioning engine may also be respectively adopted to generate an XPATH path of the web page element, for example,/html/body/form/input [ name = "user" ], as the third positioning information R3.

As an example of specific applications of the embodiment of the present application, the following sub-step may be further adopted to determine whether attribute information that can be uniquely located to a corresponding web page element exists, that is, the sub-step S2 may be referred to a processing flow chart of the attribute information of a web page element of the present application shown in fig. 4, and the specific sub-steps are as follows:

when step S21 is traversed: traversing a web page element set of the web page to be detected by adopting current attribute information combination to obtain a current set and a current number of the positioned web page elements;

next traversal of step S22: traversing the current set obtained in the current traversing step by adopting a next attribute information combination to obtain a next set and a next quantity of the positioned web page elements; the next attribute information combination comprises information in the current attribute information combination and newly added attribute information;

a judgment step S23 of judging whether the next number is less than or equal to the current number, and whether the next number is 1; if yes, execute success determination step S24; if not, executing an attribute information conversion step S25;

a success determination step S24 of determining that the attribute information of the corresponding web page element can be uniquely located by combining the attribute information of the next time;

an attribute combination converting step S25, re-executing the next traversal step S22, with the next attribute information combination as the current attribute information combination, the next set as the current set, and the next number as the current number.

In the embodiment of the present invention, it is assumed that attribute information "tagName": INPUT "," name ": user", "type": text "," value ": 1" of a web page element exists, if the current attribute information combination tagName "is adopted, the" INPUT "traverses the web page element set of the web page to be detected, the current set and the current number of the located web page elements are obtained, the next attribute information combination tagName": INPUT "," name ": user" traverses the current set, the next set and the next number 4 are obtained, since the next number 4 is smaller than the current number 5, the next attribute information combination is used as the current attribute information combination, the next set is used as the current set, the next number 4 is used as the current number 4, the next traversal step is executed again, and then the next attribute information combination is tagName ": INPUT", "next attribute information combination, and the name, the user, the type, the text are combined by adopting the next attribute information, the tagName, the INPUT, the name, the user, the type, the text are traversed through the current set, and the next set and the next quantity 1 of the positioned web page elements are obtained. Since the next number 1 is smaller than the current number 4 and the next number is 1, the next attribute information combination tagName ": INPUT", "name": user "," type ": text" is determined to be the attribute information that can be uniquely located to the corresponding web page element.

If other attribute information exists when the next quantity is 1, then other attribute information can be continuously added to continuously traverse the web page element set of the web page to be detected, and the obtained attribute information with the next quantity still being 1 is used as positioning information to form an attribute combination of the web page elements, and the attribute combination is used as first positioning information R1, so that the accuracy of the obtained web page element positioning information is improved.

It should be noted that the web page element can be correctly positioned only at the next time and when the number of times is equal to and equal to 1; if the number of the obtained current time is 1 for the first time and the number of the positioned web page elements calculated for other times is 0, the method indicates that only one web page element of the web page to be detected and the web page element to be found have the same value on the attribute information of the attribute information combination adopted for the first time, so the matching degree is not high and the condition for searching the web page element is not met; if the current number obtained for the first time is 0, the web page element positioning fails, and the web page element to be found cannot be positioned in the web page to be detected; if the current number obtained for the first time is greater than 1, but the number calculated for multiple subsequent times is not 1, it indicates that the positioning of the web page element at this time fails, and in order to save resources, the operation of obtaining the first positioning information R1 on the web page element may be stopped.

The following description will be given to a preferred example of the steps of determining whether there is attribute information that can be uniquely located to a corresponding web page element in the present application, with reference to a flowchart for determining attribute information of a web page element in the present application shown in fig. 5, and the specific steps are as follows:

substep SS21, traversing the web page element set of the web page to be detected by adopting the first attribute information combination, and obtaining a first set and a first quantity of the positioned web page elements; wherein the first attribute information combination includes first attribute information;

in a specific implementation, the attribute information may include an attribute name and a corresponding attribute value, where the first attribute name of the first attribute information may be a designated attribute name, and as an example, the designated attribute name may conform to a non-null attribute name specified by an HTML protocol, such as a tagName and a nodeName, and of course, other designated attribute names may be used, which is not limited in this application.

Sub-step SS22, traversing the first set by adopting the second attribute information combination to obtain a second set and a second quantity;

wherein the second attribute information combination comprises the first attribute information and second attribute information;

sub-step SS23, determining whether the first number is greater than or equal to the second number, if yes, performing sub-step SS24, and if no, performing sub-step SS 26;

substep SS24, determining whether said second number is 1; if yes, go to substep S210, if no, go to substep SS 25;

sub-step SS25, traversing the second set by adopting the third attribute information combination, and obtaining the number of the currently positioned web page elements as a third number;

wherein the third attribute information includes the first attribute information, the second attribute information, and third attribute information;

sub-step SS26, traversing the first set by adopting the third attribute information combination, and obtaining the number of the currently positioned web page elements as a third number; go to substep SS 27;

substep SS27, determining whether there is other attribute information, if yes, executing substep SS28, otherwise, executing substep SS 29;

substep SS28, returning to substep SS22 after the third attribute information combination is used as the first attribute information combination and one additional attribute information is added in the third attribute information combination as the second attribute information combination;

sub-step SS29, when the third number is 1 and the second number is greater than or equal to the third number, combining the third attribute information, and determining that the attribute information can be uniquely located to the corresponding web page element; otherwise, judging that the corresponding web page element cannot be uniquely positioned;

and a sub-step SS210 of combining the second attribute information and determining that the attribute information can be uniquely located to the corresponding web page element.

Assuming that attribute information 'tagName': INPUT ',' name ': user', 'type': text ',' value ': 1' of web page elements exists, if a first attribute information combination tagName ': INPUT' is adopted to traverse a web page element set of a web page to be detected, a first set and a first quantity 5 are obtained, a second attribute information combination tagName ': INPUT', 'name': user 'is adopted to traverse the first set, a second set and a second quantity 4 are obtained, and since the first quantity 5 is larger than the second quantity 4, a third attribute information tagName': INPUT ',' name ': user' and a type ': text' of the web page elements are continuously adopted to traverse the second set. If the other attribute information "value": 1 "of the web page element is used as the first attribute information combination, and one additional attribute information is added to the third attribute information combination to form a new second attribute information combination tagName": INPUT "," name ": user", "type": text "," value ": 1", and so on until the third number is 1 and the second number is greater than or equal to the third number, the third attribute information combination is determined as the attribute information that can be uniquely positioned to the corresponding web page element, for example, if the third attribute information combination tagName ": INPUT", "name": user "," type ": text" is positioned to the web page element in the third number of 1, the third attribute information combination may be determined as the third attribute information combination, "name": user "," type ": text" can be uniquely located to the attribute information of the corresponding web page element.

Of course, it may also be possible to traverse the first set by using the second attribute information combination tagName ": INPUT", "name": user "to obtain that the number of currently located web page elements is the second number 1, and then it may also be determined that the second attribute information combination tagName": INPUT "," name ": user" may uniquely locate the attribute information of the corresponding web page element at this time.

In order to further understand the embodiment of the present application, a specific example is used to describe the process of acquiring the first positioning information R1 according to the embodiment of the present application.

Assuming that attribute information "tagName": INPUT "," name ": user", "type": text "," value ": 1" of the web page element exists, traversing the web page to be detected by using the attribute information, and obtaining the number of the located web page elements, the table of the number of the located web page elements may be specifically referred to as shown in table 1 below:

as can be seen from table 1, the attribute information specified by the web page element is obtained as the current attribute information combination "tagName": INPUT ", the current attribute information combination" tagName ": INPUT" is used to traverse the web page element set of the whole web page to be detected, the number 5 of the elements positioned on the web page is obtained, then the attribute information is increased one by one and the number of the elements positioned on the web page is obtained, and when the obtained number of the elements positioned on the web page is 1, the corresponding attribute information is obtained to form an attribute combination as the first positioning information R1. It is easy to see that, when the number of web page elements located by "tagName": INPUT "+" name ": user" + "type": text "+" value ": 1" is 1, the above attribute information may be recorded to obtain the own attribute combination { "tagName": INPUT "," name ": user", "type": text "," value ": 1") of the web page as the first location information R1.

As an example of specific applications of the embodiment of the present application, the following sub-step may be further adopted to determine whether there is attribute information that can be uniquely located to a parent element of a corresponding web page element, that is, the sub-step S5 may refer to a processing flow chart of attribute information of a parent element of a web page element of the present application shown in fig. 5, where the specific steps are as follows:

a parent class current traversal step S31, wherein the parent class element set of the web page elements of the web page to be detected is traversed by adopting the attribute information combination of the current parent class elements, and the current set and the current number of the located parent class elements of the web page elements are obtained;

a parent next traversal step S32, which is to traverse the current set of parent elements obtained in the parent current traversal step by using the attribute information combination of the next parent element, to obtain a next set and a next number of the parent elements of the located web page elements; the next attribute information combination of the parent element comprises information in the current attribute information combination of the parent element and attribute information of a newly added parent element;

a parent class determination step S33 of determining whether the next number is less than or equal to the current number, and whether the next number is 1; if yes, go to the father class success determination step S34; if not, executing a parent attribute information conversion step S35;

a parent success determination step S34 of combining the attribute information of the next parent element and determining that the attribute information of the parent element that can be uniquely positioned to the corresponding web page element is present;

a parent attribute combination converting step S35, regarding the attribute information combination of the next parent element as the attribute information combination of the current parent element, regarding the next set as the current set, regarding the next number as the current number, and re-executing the next parent traversal step S32.

In the embodiment of the application, if the attribute information ' tagName ': form ' and ' index ': 1 ' of the parent element of the web page element exists, if the attribute information combination ' tagName ': form ' of the current parent element is adopted, the parent element set of the web page element of the web page to be detected is traversed, and the current set and the current number 3 of the parent element are obtained; and traversing the current set of the parent elements by adopting the attribute information combination 'tag name': form ',' index ': 1' of the next parent element to obtain the next set and the next quantity 1 of the parent elements of the positioned web page elements. Since the next number 1 of the parent element is smaller than the current number 3 of the parent element, and the next number of the parent element is 1, the next attribute information of the parent element may be combined with "tagName": form "and" index ": 1" to determine that the attribute information of the parent element can be uniquely located to the corresponding web page element.

The following description will be given to a preferred example of the step of determining whether there is attribute information that can be uniquely located to a parent element of a corresponding web page element in the present application, with reference to a flowchart for determining attribute information of a parent element of a web page element in the present application shown in fig. 6, and the specific steps are as follows:

sub-step SS31, traversing the web page element set of the web page to be tested by adopting a fourth attribute information combination to obtain a third set and a fourth quantity;

wherein the fourth attribute information combination includes fourth attribute information;

substep SS32, traversing the third set by adopting a fifth attribute information combination to obtain a fourth set and a fifth quantity;

wherein the fifth attribute information combination includes the fourth attribute information and fifth attribute information;

sub-step SS33, determining whether the fourth number is greater than or equal to the fifth number, if yes, performing sub-step SS34, and if no, performing sub-step SS 36;

substep SS34, determining whether said fifth number is 1; if yes, go to substep S310, otherwise go to substep SS 35;

sub-step SS35, traversing the fourth set by adopting a sixth attribute information combination, and obtaining the number of the currently positioned web page elements as a sixth number;

wherein the sixth attribute information includes the fourth attribute information, fifth attribute information, and sixth attribute information;

sub-step SS36, traversing the third set by adopting a sixth attribute information combination, and obtaining the number of the currently positioned web page elements as a sixth number; go to substep S37;

substep SS37, determining whether attribute information of other parent elements exists, if yes, executing substep SS38, otherwise, executing substep SS 39;

substep SS38, using the sixth attribute information combination as a fourth attribute information combination, and returning to substep SS32 after adding an attribute name and a corresponding attribute value of the other parent class element as a fifth attribute information combination in the sixth attribute information combination;

sub-step SS39, when the sixth number is 1 and the fifth number is greater than or equal to the sixth number, combining the sixth attribute information and determining that the attribute information can be uniquely located to the corresponding parent element; otherwise, judging that the corresponding parent class element cannot be uniquely positioned;

and a substep SS310 of combining the fifth attribute information and determining attribute information that can be uniquely located to the corresponding parent element.

Assuming that attribute information ' tagName ': form ', ' index ': 1 ' of a parent element of a web page element exists, if a fourth attribute information combination ' tagName ': form ' is adopted to traverse a web page element set of a web page to be detected to obtain a third set and a fourth quantity 3, a fifth attribute information combination ' tagName ': form ', ' index ': 1 ' is adopted to traverse the third set to obtain a fourth set and a fifth quantity 1, and because the fourth quantity 3 is greater than the fifth quantity 1, a sixth attribute information combination is adopted to traverse the fourth set to obtain a sixth quantity. Judging whether attribute information of other parent elements exists or not, if so, combining the sixth attribute information to serve as a fourth attribute information combination, combining and adding attribute information of one other parent element in the fifth attribute information to serve as a fifth attribute information combination, and so on, and when the sixth number is 1 and the fifth number is greater than or equal to the sixth number, combining the sixth attribute information to judge that the attribute information of the corresponding parent element can be positioned; otherwise, the attribute information of the corresponding parent class element cannot be positioned. In this example, since the obtained fifth number is 1, it may be determined that the fifth attribute information combination tagName ": form", "index": 1 "may be uniquely located to the attribute information of the corresponding web page element.

In a specific implementation, the number of the located web page elements that can be obtained only by adopting the attribute information combination with a plurality of attribute information is 1, or the number of the parent elements that can be obtained only by adopting the attribute information combination with a plurality of parent elements is 1; the number of the located web page elements may be 1 by using only the attribute information combination of the two attribute information, or the number of the parent elements of the located web page elements may be 1 by using only the attribute information combination of the attribute information of the two parent elements, which is determined by the condition of the web page element set in the specific web page to be detected, and the embodiment of the present application does not limit this.

It should be noted that the three types of generation manners of the positioning information R1, R2, and R3 are only examples, and in a specific implementation, other generation manners of the positioning information may be adopted according to an actual situation, for example, the positioning information of the web page element is generated by a table of the web page to be tested, which is not limited in this embodiment of the present application.

Step 102, determining the optimal positioning information in the at least two pieces of positioning information;

in a preferred embodiment of the present application, the step 102 may comprise the following sub-steps:

step S102-1, counting time consumed by adopting the first positioning information to position web page elements of the web page to be detected as first processing time;

step S102-2, counting time consumed for positioning web page elements on the web page to be detected by adopting the second positioning information as second processing time;

step S102-3, counting time consumed for positioning web page elements on the web page to be detected by adopting the third positioning information as third processing time;

and a substep S102-4 of performing reverse ordering on the first processing time, the second processing time and the third processing time, and extracting positioning information corresponding to the processing time with the highest ordering as optimal positioning information.

If three types of positioning information, namely R1, R2 and R3, are acquired by the information extraction device, the time consumed for positioning web page elements in a web page element set of a web page to be measured is counted respectively, and priority ranking is performed according to the processing time consumed by the three types of positioning information, for example, reverse ranking can be performed according to the time length, and the positioning information ranked at the top is used as the optimal positioning information. For example, if the processing time of the third positioning information R3 is shortest, the third positioning information R3 is set as the optimal positioning information.

Of course, the determination of the optimal positioning information is only an example, for example, some positioning information may also be directly selected as the optimal positioning information, and when the embodiment of the present application is implemented, the optimal positioning information may be determined in a manner according to an actual situation, which is not limited in this embodiment of the present application.

And 103, when the web page element cannot be positioned by adopting the optimal positioning information and at least one piece of other positioning information which can be positioned to the web page element exists, adopting the other positioning information to update the optimal positioning information.

As a preferred embodiment of the present application, the step 103 may include the following sub-steps:

substep S103-1, adopting the other positioning information as the optimal positioning information;

if the web page to be detected is changed and the optimal positioning information cannot be positioned to the web page element, other positioning information capable of being positioned to the web page element can be selected to replace the original optimal positioning information. For example, when the optimal positioning information R3 cannot be positioned to a web page element, the first positioning information R1 may be selected as the optimal positioning information, and the re-determined optimal positioning information R1 is updated to the multi-dimensional positioning information system.

As another preferred embodiment of the present application, the step 103 may include the following sub-steps:

and a substep S102-2 of repairing the optimal positioning information by using the other positioning information.

If the optimal positioning information cannot be positioned to the web page element and at least one piece of other positioning information can still be positioned to the web page element, then the related positioning information can be extracted from the positioning information which can still be positioned to the web page element to repair the optimal positioning information, so that the optimal positioning information can still continue to position the web page element, for example, when the optimal positioning information R3 cannot be positioned to the web page element, if the first positioning information R1 can still be positioned to the web page element, the related positioning information can be extracted from the first positioning information R1 to be updated to the optimal positioning information R3, the repair to the optimal positioning information R3 is completed, and finally, the re-determined optimal positioning information R3 is updated to the multi-dimensional positioning information system through a feedback device.

Referring to fig. 8, a flowchart illustrating steps of embodiment 2 of a method for positioning web page elements according to the present application is shown, where the method specifically includes the following steps:

step 201, acquiring positioning information of at least two web page elements in a web page to be detected;

step 202, determining optimal positioning information in the positioning information of the at least two web page elements;

step 203, when the web page element cannot be positioned by using the optimal positioning information and at least one piece of other positioning information which can be positioned to the web page element exists, updating the optimal positioning information by using the other positioning information;

and step 204, positioning the web page element by using the optimal positioning information.

In a preferred embodiment of the present application, when the optimal positioning information is the first positioning information R1, the step 204 may include the following sub-steps:

a current traversing step S41 is positioned, and a current attribute information combination is adopted to traverse the web page element set of the web page to be detected, so as to obtain a current set and a current number of the positioned web page elements;

a next traversal positioning step S42, wherein a next attribute information combination is adopted to traverse the current set obtained in the current traversal positioning step, so as to obtain a next set and a next quantity of the positioned web page elements; the next attribute information combination comprises information in the current attribute information combination and newly added attribute information;

a positioning determination step S43 of determining whether the next number is less than or equal to the current number, and whether the next number is 1; if yes, execute positioning success determination step S44; if not, executing a positioning attribute combination conversion step S45;

a positioning success determination step S44 of determining that the web page element is positioned by using the optimal positioning information;

and a positioning attribute combination converting step S45, re-executing the next traversal step, with the next attribute information combination as the current attribute information combination, the next set as the current set, and the next number as the current number.

In this embodiment of the application, when the optimal positioning information is the first positioning information R1, the corresponding attribute information may be read from the attribute combination of the web page element itself, the read attribute information is superimposed one by one and the web page element set of the web page to be detected is traversed in multiple times, until the number of currently positioned web page elements is 1, the web page element is uniquely positioned.

For example, assume that the attribute combinations are the following attribute names: (tagName \ name \ type \ value) (allowing the attribute values of some attribute information to be null), the process of using the first positioning information R1 to position the web page element is shown in the following table 2:

as can be seen from table 2, the attribute information is added one by one to locate the web page elements, and when the number of located web page elements is 1, the web page elements are located.

Firstly, extracting specified attribute information 'tagName' from attribute combination, using 'INPUT' as current attribute information combination, supposing that current attribute information combination is adopted, traversing a web page element set of a web page to be detected to obtain a current set and a current number of positioned web page elements, 5, using next attribute information combination 'tagName', using 'INPUT' + 'name', using ', traversing the current set obtained in the current traversing step to obtain a next set and a next number 3 of positioned web page elements, since the next number 3 is less than the current number 5, using the next attribute information combination as the current attribute information combination, using the next set as the current set, using the next number 3 as the current number 3, re-executing the next traversing step, and then combining the next attribute information combination into' tagName '+' name ', user' + 'type', and the like, until the web page elements are positioned to the number of 1 when the attribute combination of 'tagName': INPUT '+' name ': user' + 'type': text '+' value ': 1' is adopted.

The following description will be given of a preferred example of the step of positioning a web page element by using the optimal positioning information, with reference to a flowchart of positioning a web page element in the present application shown in fig. 9, and the specific steps are as follows:

sub-step SS41, traversing the web page element set of the web page to be tested by adopting the first attribute information combination to obtain a first set and a first quantity;

wherein the first attribute information includes first attribute information;

sub-step SS42, traversing the first set by adopting the second attribute information combination to obtain a second set and a second quantity;

sub-step SS43, determining whether the first number is greater than or equal to the second number, if yes, performing sub-step SS 44; if not, go to sub-step SS 46;

substep SS44, determining whether said second number is 1; if yes, performing sub-step SS411, otherwise, performing sub-step SS 45;

sub-step SS45, traversing the second set by adopting the third attribute information combination, and obtaining the number of the currently positioned web page elements as a third number;

sub-step SS46, traversing the first set by adopting the third attribute information combination, and obtaining the number of the currently positioned web page elements as a third number;

sub-step SS47, determining whether the second number is 1, and if the first number is greater than or equal to the second number, performing sub-step SS 48; if not, go to sub-step SS 49;

sub-step SS48, determining to position to the web page element using the optimal positioning information;

substep S49, determining whether there is other attribute information, if yes, executing substep S49, otherwise, executing substep SS 410;

substep SS410, using said third attribute information combination as a first attribute information combination, and adding one of said other attribute information combinations as a second attribute information combination in said third attribute information combination, and returning to said substep SS 42;

sub-step SS411, determining that the web page element cannot be located using the optimal location information.

Referring to table 2, first, the specified attribute information "tagName": INPUT "is extracted from the attribute combination as the first attribute information combination, assuming that the first attribute information combination" tagName ": INPUT" is used to correspondingly locate the first number of web page elements to 5 and obtain the first set, and the second attribute information combination "tagName" + "name": user "is used, the second attribute information combination traverses the first set to correspondingly locate the second number of web page elements to 3 and obtain the second set, since the first number 5 is greater than the second number 3, the third attribute information combination traverses the second set, the third number of web page elements to 2 is located, and at the time, the web page elements are not located successfully, the third attribute information combination" tagName "+" name ": user" is used as the first attribute information combination, and the new attribute name "new name" is formed in the second attribute information combination of the other attribute information combinations of the third attribute information combination "user" + "type": text ", and so on, until the number of web page elements is 1, the web page element is located. Since the number of the web page elements positioned to be 1 is "1" in this example using the attribute combinations "tagName": "INPUT" + "name": user "+" type ": text" + "value": 1", it can be judged that the web page elements are positioned to be using the attribute combinations" tagName "+" name ": user" + "type": text "+" value ": 1".

When the optimal positioning information is the second positioning information R2, the step 204 may include the following sub-steps:

a parent positioning current traversal step S51, wherein a parent element set of the web page elements of the web page to be detected is traversed by adopting attribute information combination of the current parent element, and a current set and a current number of the located parent elements of the web page elements are obtained;

a parent positioning next traversal step S52, wherein the current set obtained in the parent positioning current traversal step is traversed by adopting the attribute information combination of the next parent element, and the next set and the next quantity of the parent elements of the positioned web page elements are obtained; the next attribute information combination of the parent element comprises information in the current attribute information combination of the parent element and attribute information of a newly added parent element;

a parent positioning determination step S53 of determining whether the next number is less than or equal to the current number, and whether the next number is 1; if yes, executing a parent class positioning success determination step S54; if not, executing a parent positioning attribute information conversion step S55;

a parent positioning success determining step S54 of combining the attribute information of the next parent element, determining that the attribute information of the parent element corresponding to the web page element can be uniquely positioned, and proceeding to the relative position positioning step;

a parent positioning attribute combination converting step S55 of re-executing the next parent positioning traversal step S52, with the attribute information combination of the next parent element as the attribute information combination of the current parent element, the next set as the current set, and the next number as the current number;

a step S56 of locating the web page element according to the relative position of the web page element within the range of the parent element, and then determining to locate the web page element by using the optimal location information.

Specifically, since the positioning process of the parent element of the web page element is the same as the positioning process of the web page element, it is not repeated here. The whole positioning process of the second positioning information R2 can be divided into 2 blocks: and the first block is used for positioning the parent element of the web page element according to the positioning information of the parent element. And the second block is used for positioning the parent element of the web page element based on the positioning information of the parent element, finding the relative position of the web page element in the range of the parent element and positioning the web page element.

The following description will be given to a preferred example of the step of determining whether there is attribute information that can be uniquely located to a corresponding web page element in the present application, referring to a locating flow chart of a parent element of a web page element in the present application shown in fig. 10, and the specific steps are as follows:

sub-step SS51, traversing the web page element set of the web page to be tested by adopting a fourth attribute information combination to obtain a third set and a fourth quantity;

substep SS52, traversing the third set by adopting the fifth attribute information combination, and obtaining the number of the currently positioned parent elements as a fifth number;

substep SS53, determining whether the fourth number is greater than or equal to the fifth number, if yes, executing substep SS54, and if no, executing substep SS 55;

substep SS54, determining whether said fifth number is 1; if yes, performing sub-step SS511, otherwise, performing sub-step SS 56;

sub-step SS55 uses sixth attribute information combination to traverse the fourth set, and obtains the number of the currently positioned web page elements as a sixth number;

wherein the sixth attribute information combination includes the fourth attribute information, fifth attribute information, and sixth attribute information;

sub-step SS56, traversing the third set by adopting a sixth attribute information combination, and obtaining the number of the currently positioned web page elements as a sixth number;

substep SS57, determining whether the sixth number is 1, and if the fifth number is greater than or equal to the sixth number, executing substep SS511, if not, executing substep SS 59;

substep S58, determining the parent element located to the corresponding web page element using the sixth attribute information and executing substep SS 512;

substep SS59, determining whether attribute information of other parent elements exists, if yes, executing substep SS510, otherwise, executing substep SS 511;

substep SS510, taking the sixth attribute information combination as a fourth attribute information combination, adding an attribute name and a corresponding attribute value of another parent element in the sixth attribute information combination as a fifth attribute information combination, and returning to substep SS 52;

sub-step SS511, judging that the web page element can not be positioned by adopting the optimal positioning information;

substep SS512, if the web page element is positioned according to the relative position of the web page element in the range of the parent element, judging to adopt the optimal positioning information to position the web page element; otherwise, judging that the web page element cannot be positioned by adopting the optimal positioning information.

When the optimal positioning information is the third positioning information R3, the step 204 may include the following sub-steps:

and a substep S61, locating said web page element using said XPATH path.

In the embodiment of the present application, when the optimal positioning information is the third positioning information R3, the web page element can be found and positioned according to the XPATH path on the web page to be detected by using the XPATH language.

Assuming that the third positioning information R3= html/body/form/input [ name = "user" ], the child element body of html, the child element form in body, and the web page element with the user name "user" in the user input box input of the child element in form are searched for in the web page to be tested according to the third positioning information R3.

a feedback device 403, configured to update the optimal positioning information with the other positioning information when the web page element cannot be positioned with the optimal positioning information and there is at least one piece of other positioning information that can be positioned to the web page element.

The web page element positioning system may implement a function of performing multi-dimensional positioning on each web page element in a web page to be detected, and specifically, the web page element positioning system may include an information extraction apparatus 401 for executing step1, a positioning engine apparatus 402 for executing step2, and a feedback apparatus 403 for executing step 3.

The page1 in fig. 8 is a dom (Document object model) tree of a dynamic web page to be tested, the information extraction device 401 can obtain multi-dimensional positioning information of web page elements of the web page to be tested (i.e., positioning information of at least two web page elements of the web page to be tested), after the layout structure of the page1 or the attribute information or other factors of the web page elements of the page1 change into the page2, the positioning engine device 402 can still position the changed web page elements by using the multi-dimensional positioning information of the web page elements, the feedback device 403 can update the multi-dimensional positioning information by using the positioned positioning information of the changed web page elements, and the positioning information of the changed web page elements is repaired.

The following is further explained for Step 1-Step 3:

Step1:

the information extraction device 401 may obtain three pieces of positioning information of the web page to be detected, which may specifically include: first positioning information R1 formed by attribute combinations of the web page elements themselves; second positioning information R2 formed by a combination of attributes of a parent class element of the web page element and the relative position of the web page element in its parent class element; third positioning information R3 formed by the XPATH path of said web page element.

The information extraction apparatus 401 can create a plurality of positioning information at a time, and thus can realize dual security of attribute positioning (R1 + R2) and coordinate positioning (R3).

Step2:

The positioning engine device 402 plays back the positioning information acquired by the information extraction device 401, performs web Page element positioning on the Page2 with the changed web Page layout to be detected, and checks whether the positioning information can also position the web Page element. In particular, using the positioning engine apparatus 402 may include the following processes:

1, selecting the positioning information with the highest priority for positioning processing, for example, the positioning information may be the third positioning information R3;

2, sequentially reading the attributes by using a positioning engine corresponding to the first positioning information R1, and respectively judging until only one web page element is positioned;

3, using a positioning engine corresponding to the second positioning information R2 to perform R1 engine positioning on the parent element of the web page element, and then positioning through the relative position sorting index of the web page element in the parent element;

and 4, positioning by using an XPATH positioning engine corresponding to the third positioning information R3 and a standard XPATH syntax parsing engine.

Step3:

The feedback means 403 repairs the positioning information acquired by the information extraction means 401 by the execution result of the played-back positioning engine means 402. Whether the priority of the information extraction device 401 is still unchanged in the positioning engine can be judged firstly, if the priority is unchanged, the optimal positioning information is still effective, the repairing is not needed, if the priority is changed, the positioning information of the web page elements needs to be repaired, the positioning information is obtained again through the information extraction device 401 and is fed back to the web page element positioning system for updating, and the self-repairing processing of the positioning information is carried out on the changed web page elements.
