Background technology
Any a product all needs to test before putting goods on the market, and test process just needs the participation of test case (test case).Test case is meant a group of test input, executive condition and expected results developing for specific objective, and its target can be certain Program path of test or examine and whether satisfy certain specific demand.That is to say that test case has instructed the direction of test, the correct output result who has defined the scope that need test, needed test contents and expection.
There are two kinds of method of testings at present in the prior art: Black-box Testing and white-box testing, wherein Black-box Testing (perhaps is called functional test, or data-driven test) is meant according to the function design specification of known product product tested whether meet the requirements with each function of verifying product; White-box testing (perhaps is called structured testing, or logical drive test) is meant according to the internal work process of known product product is tested, whether each built-in function with the checking product meets the design specification requirement, and whether all internal components are through checking.
In the Black-box Testing process, test is carried out at the interface of software, promptly tested object is regarded as a black box, the tester does not consider the logical organization and the bulk properties of tested object program inside, only need the description according to program, the function of the scrutiny program function whether instructions up to specification requires gets final product.Black-box Testing is mainly used in finds following a few class mistakes:
Whether wrong or omit function;
Can what can input correct on interface be accepted or exports correct result;
Whether data structure mistake or external information (for example data file) access errors is arranged;
Whether can meet the demands on the performance;
Whether mistake of initialization or termination property or the like is arranged.
In the white-box testing process, need carry out careful inspection to the details of tested software, promptly tested object is regarded as a box of opening, the tester utilizes the logical organization of program inside to reach for information about, design or selection test case are to test (promptly whether consistent with expecting state with definite virtual condition by the state at the difference scrutiny program) to all logical paths of program.White-box testing is mainly used in to be checked program module, such as: to program module all independently execution route carry out at least one all over the test; Carry out at least one to all logic decision (getting " very " and two kinds of situations of getting " vacation ") all over test; In the boundary of round-robin border and operation, loop body is tested; And the validity of testing inner data structure or the like.
In the test process of reality, test result and the inconsistent phenomenon of expected results appear through regular meeting, and industry is referred to as bug with these inconsistent phenomenons.According to the difference of bug generation reason, bug can be divided into bug and the outer bug of test case in the test case.Wherein the outer bug of test case is meant in test process, except that inspection according to the test case regulation, might be because some fortuitous events (such as the plug of port, specific temperature humidity and carrying out when interconnected or the like) with certain equipment, expose some problems of tested equipment, these fortuitous events are referred to as the outer bug of test case.
As shown in Figure 1,,, the generative process of test case in the prior art is described below in conjunction with Fig. 1 for the generative process synoptic diagram of current tested object test case in the prior art, as follows:
Generate the test case of current tested object according to description, this test case comprises test function and content measurement;
Test case according to above-mentioned generation is tested current tested object;
After test is finished, directly, add in the test case of this tested object the outer bug of the test case that produces in the test process.
Owing to only generate test case usually in the prior art, and do not consider therefore to make other factors of more more needing of details, test and the relatively thicker condition of test result can not satisfy the requirement that makes that as required test result is more detailed-oriented according to description; Further, owing to prior art is applied directly to the outer bug of the test case that produces in the test process in the test case of this tested object, therefore this application is contributed and can not produce other test products object only at this measuring object.

Wherein the test case generation system can pass through client/server (C-S, Client/Server) framework software is realized, as shown in Figure 4, be the implementation process synoptic diagram of embodiment of the invention method for generating test case in test case generation system of the present invention, the cause information attending device that bug shown in Fig. 4 produces is the first above-mentioned attending device, the second above-mentioned in addition attending device can place the use-case generating apparatus, also can be provided with separately, be that example illustrates second attending device is placed the use-case generating apparatus among Fig. 4, therefore second attending device is not shown in this Figure.Wherein the use-case generating apparatus can place client, promptly the use-case generating apparatus can be installed on each Test Engineer's the work PC, the Test Engineer is by operation use-case generating apparatus on PC, the cause information of safeguarding in the cause information attending device that the use-case generating apparatus of this operation will produce bug is automatically downloaded, and carry out corresponding coupling with the test specification descriptive information, generate and be used for test case that product is tested, if second attending device is provided with separately, then also to from second attending device, download the test specification descriptive information.
Wherein the cause information of the cause information attending device maintenance of bug generation is included in the bug that sets in advance before the test and produces cause information, and then can also comprise that the new bug that receives produces cause information from the external world, in addition can for the bug that obtains of test in test process not when the row of the cause information that sets in advance, with the bug output that test obtains, analyze the new bug that obtains by extraneous Test Engineer according to the bug that exports and produce cause information.This shows that along with constantly carrying out of test, the bug of maintenance produces cause information in continuous increase, thereby make and generate that to be used for test case coverage rate that subsequent product is tested increasing, more and more higher to the test accuracy of product.
Elaborate the concrete course of work of the cause information attending device of bug generation below:
This device inside can be safeguarded " TestClear " data structure in advance, artificial experience according to the Test Engineer, can in this data structure, write all kinds of common bug in advance and produce cause information, promptly before program comes into operation first, in " TestClear " data structure, defined some common bug and produced cause information.For example, the bug that has write among the TestClear produces cause information can be as shown in table 1 below:
The bug that has write among the table 1:TestClear produces the cause information table
| Type of physical port |
| CPU and internal memory |
| The incoming message condition |
| The logic interfacing attribute |
| Routing property |
| The operating process relevant with order is set |
| Function uses restriction special |
| Relation with other modules |
| The ultimate value factor |
| Performance factor (time/CPU, memory usage) |
| Intercommunity with other manufacturers |
| Resource contention is with shared |
| The specific demand of particular client |
| Abnormal operation and abnormal data |
| Both property used had both been inserted |
In the process that product is tested, this device imports whole Bug that test produces, if the generation reason of a bug, then is referred to this bug " bug in the use-case " at the row of above-mentioned tabulation; If the generation reason of a bug at the row of above-mentioned tabulation, then is not referred to this bug " with exception bug ":
With " with exception bug " that counts, carry out priority queueing according to the indexs such as frequency of the order of severity, appearance, and the result after will lining up presents to the Test Engineer.
The Test Engineer can analyze each " with exception bug " according to the object information that presents, and sums up the general character cause information, forms new bug and produces cause information, and the new cause information that forms is added in the above-mentioned TestClear data structure; Wherein, also it can be added to respectively in the above-mentioned TestClear data structure for the bug that can't put out the general character cause information in order.
Follow-up can be with reference to the TestClear clauses and subclauses of having added behind the new cause information, cease with the product requirement specification letter, generate new test case, be used for next product is tested, therefore along with constantly carrying out of testing, because the TestClear clauses and subclauses are more and more, therefore the test case that generates is more and more detailed, and is just more and more accurate to the test of subsequent product.
Wherein, can be divided into following a few class to the cause information of bug generation:
1, after certain path, complicated, the repeatable operation, disabler appears
Definition: this specific operation may be the process of constantly adding deletion, or the different parameters of order directly switches, or is the variation of correlation function.The process that these operations change might cause certain order input back invalid, even the unusual deadlock that brings switch.
2, certain function goes wrong when using with other function associations
Definition: when a plurality of functions are used simultaneously produce because share CPU, internal memory, medium resource fight for or shared, and have problems.
3, port type coverage rate deficiency
Definition: the whole type of physical ports and the logic port type that do not cover tested product.
4, the result judges deficiency
Definition: in the result's judgement to certain test process, have problem unilateral, distortion, can transmit, but do not judge the speed that message is transmitted or transmit the message content of coming out such as message under the uniform temperature condition.
5, the coverage rate deficiency of incoming message
Definition: various types of incoming messages of not considering possible data communication products.
6, CLI does not reach whole coverings
Definition: do not cover the complete order that has realized at present.
7, index does not reach whole coverings
Definition: do not satisfy description.
This device can also be transformed into the file with forms such as .jpg .xls .csv .txt .xml with the TestClear items for information that adds behind the new cause information, outputs to central server.
Except using the above-mentioned TestClear data structure that provides, the embodiment of the invention can also use other data structures to carry the cause information that all kinds of bug produce.
Elaborate the concrete course of work of use-case generating apparatus below again:
The cause information attending device exchange message that this device can produce with bug, with the input of the TestClear items for information after the cause information attending device processing of bug generation as self, with the test specification instructions, match the test case that is used for next product test.
Second attending device that wherein is used for maintenance test specification information can initiatively receive the test specification descriptive information of extraneous input, also can use the form that imports the .xls file, from a file, import the test specification descriptive information, can also from the server that stores the test specification descriptive information, download the test specification descriptive information.
The use-case generating apparatus can be downloaded up-to-date TestClear clauses and subclauses file automatically from the cause information attending device that bug produces, select the corresponding item entries in the TestClear clauses and subclauses, go the corresponding item entries in the matching test specification information, satisfy the test case of new product test request with generation.
Wherein, can adopt following variety of way to generate new test case based on up-to-date TestClear clauses and subclauses and test specification descriptive information:
Mode one: near one item missing TestClear items for information mates with every test specification descriptive information respectively; Obtain each occurrence of obtaining of coupling as test case.Be that some TestClear clauses and subclauses of mandatory requirement must be mated with any one test specification descriptive information respectively, these TestClear clauses and subclauses can be defined as " S level " clauses and subclauses here.Such as the test specification descriptive information has 5, has 3 " S level " clauses and subclauses in the TestClear clauses and subclauses, can match 5 * 3=15 item according to this mode so, and then can be with match these 15 as newly-generated test case.
Mode two: carry out respectively:, this TestClear items for information is mated with the every test specification descriptive information that comprises described key word respectively according to the key word that comprises in this TestClear items for information at least one TestClear items for information; Obtain at least one cause information and carry out each occurrence that obtains after the above-mentioned matching treatment, as test case.Promptly according to " keyword " information that comprises in some TestClear clauses and subclauses, those TestClear clauses and subclauses and some the test specification descriptive information that includes correspondence " key word " can only be mated, those TestClear clauses and subclauses can be defined as " L level " clauses and subclauses here.
For example: with the TestClear clauses and subclauses is that " dissimilar CPU processing poweies " are example, and the performance when handling big data quantity of these clauses and subclauses is especially obvious, and the performance of entire equipment is brought a lot of influences.So the key word that can define in these clauses and subclauses comprises: the key1=performance, key2=leads (referring to degree descriptions such as ratio, probability), key3=degree.When the test specification descriptive information is described to these key words, will be judged as automatically and need mates with " dissimilar CPU processing poweies " item.
Mode three: carry out at least one TestClear items for information:, in all test specification descriptive information items, choose the test specification descriptive information item of corresponding ratio according to the scale parameter that comprises in this TestClear items for information; And this TestClear items for information mated with the every test specification descriptive information that selects respectively; Obtain at above-mentioned at least one TestClear items for information and carry out each occurrence that obtains after the matching treatment, as test case.Be to comprise a scale parameter information in some TestClear clauses and subclauses, according to this scale parameter, the use-case generating apparatus can be chosen the test specification descriptive information item of corresponding ratio in all test specification descriptive information items, mate with the TestClear clauses and subclauses that comprise this scale parameter respectively, those TestClear clauses and subclauses can be defined as " R level " clauses and subclauses here.
For example, with the TestClear clauses and subclauses is that " temperature " is example, it is 5% that the scale parameter that comprises in these clauses and subclauses is set, (such as whole test specification descriptive informations is 20 to need to choose from whole test specification descriptive informations 5% content exactly, then only needing to select one just satisfies condition), under different temperature environments, test.
Mode four: test specification descriptive information of picked at random in the test specification descriptive information, and near one item missing TestClear items for information mates with the above-mentioned test specification descriptive information item of choosing respectively; Obtain each occurrence of obtaining of coupling as test case.This mode relatively is applicable to special user's demand.
Above-mentioned four kinds of matching ways can choose that wherein one or more are used in combination in concrete test process.
To enumerate an embodiment below comes test case generation scheme of the present invention is carried out better detailed elaboration.It is example that this embodiment tests with the software project that has increased the QINQ function to, the process that generates test case according to the present invention program is described, wherein the QINQ function mainly is to produce for the quantity space of expanding VLAN, it realizes that by increase one deck 802.1Q label again on the basis of original 802.1Q message the quantity of the VLAN that makes is increased to 4K * 4K.
