Description
Technical Field
The embodiment of the invention relates to the technical field of software testing, in particular to an accurate regression testing method and device under a micro-service architecture.
Background
In gradual and fast iterative development, the continuous release of new versions makes regression testing frequently performed, and in the continuous integration and continuous interaction process, the regression testing is required to be performed frequently and efficiently. Therefore, it is very meaningful to improve the efficiency and effectiveness of regression testing by selecting the right regression testing strategy. The regression test of the existing microservice architecture software mainly adopts the following two schemes:
(one) regression based on regression document total
In general, a regression test document is designed based on a self service system, the regression test document is manually maintained along with a project process to keep the regression test document consistent with a current system, and full regression is performed according to the regression test document during regression test. When the regression test document design is not detailed enough, supplementary test is needed to be carried out according to the experience of testers during regression, and the situation of test scene omission is easy to occur. If the regression test document design covers all scenarios in sufficient detail, the workload of regression test document maintenance and test scenario design is increased, and the cost of regression testing is increased.
(II) regression testing based on certain regression strategy and regression case set
For a relatively large micro-service project, with the increase of the service complexity, the cost of frequent total regression is too high. Many projects can make certain regression strategies according to the project conditions by means of some automatic testing tools or platforms. For example, a risk-based selection test selects a regression test set from a baseline test case base based on certain risk criteria, and generally, the test is from a primary feature to a secondary feature; the test based on a certain function importance evaluation method is to preferentially select a test case aiming at the most important or most frequently used function for testing; and the modification condition of the software is identified through manual dependency analysis, the updated influence range is determined, and regression testing is performed. In the test method, the automatic test tool mainly performs automatic test case management, execution function module maintenance, tracking and the like; the input of test cases and the division of system function modules are also in a manual maintenance mode. The efficiency and cost of the test scheme test are reduced, the quality and stability of the test are improved, but the regression test scheme and range are still manually dominant on the whole, and the quality of the test depends on the good test scheme design and execution of a team.
Therefore, the existing technical scheme mainly depends on regression testing documents and self-defined testing strategies to determine the range of each regression testing, some regression testing can be performed through an automatic testing tool, but the regression testing range is still dominated by a manual mode, and the large-range regression testing is performed under a certain strategy. The existing scheme has a plurality of problems: firstly, an accurate regression test cannot be performed, and many regression tests only do nothing. Secondly, the total regression testing cost is higher, and large-range regression testing is always carried out for ensuring the quality. Thirdly, test omission easily occurs, and the bug is not found in time.

Fig. 1 is a flowchart of an accurate regression testing method under the micro service architecture according to an embodiment of the present invention. As shown in fig. 1, the method includes:
the accurate regression testing device under the micro-service architecture firstly obtains an effective change function, wherein the effective change function is a function which is effectively changed. The effective change means that the function is substantially changed, and the function operation or the function is affected. For example, if the function is changed by adding extra empty lines, spaces, or the like, the function is not affected by the operation or function, and the function is not changed. Invalid function changes do not require regression testing and can be ignored.
The effective change function may be plural.
102, acquiring a calling function for directly and indirectly calling the effective change function based on the effective change function;
the effective change function refers to a function in which the function itself is effectively changed. Due to the software implementation process of a project, calling between functions often occurs, and if the called function is changed, the function calling the function is influenced to be changed together with the change. Therefore, in performing the regression test, not only the effective modification function but also a calling function for directly and indirectly calling the effective modification function needs to be considered. The calling functions directly and indirectly calling the effective change function are functions directly calling the effective change function and functions indirectly calling the effective change function.
When there are a plurality of effective changing functions, the calling functions corresponding to the corresponding effective changing functions need to be acquired respectively.
103, determining a change interface function list according to all the effective change functions and all the call functions, and determining a regression test range according to the change interface function list;

Specifically, comparing the changed file with the file before the change identifies all the changes of the file. And screening out the functions with effective changes from all the changes, namely obtaining the effective change functions.
On the basis of the embodiment, the embodiment of the invention obtains the effective change function by changing the file, thereby improving the obtaining efficiency and the accuracy of the effective change function and further improving the efficiency and the accuracy of the regression test.
Further, based on the above embodiment, the obtaining the effective change function according to the change file specifically includes: acquiring all effective changes appearing in the change file, and dividing all effective changes into function changes, class variable changes and annotation changes; acquiring a first class of change functions according to the change of the function, acquiring a second class of change functions according to the change of the class variable, and acquiring a third class of change functions according to the change of the annotation; and obtaining the effective change function according to the first type change function, the second type change function and the third type change function.
And after the change file is obtained, obtaining all effective changes in the change file according to the change file. When determining whether or not the change is valid, the determination may be made by excluding invalid changes, or by setting a change form of valid changes, or may be made by such a method. For example, when the determination is made by excluding the invalid change, if it is determined that the change occurred is only insertion of an empty line, the change may be determined as an invalid change; if the change that occurs does not belong to any set invalid change, it is considered to be a valid change. When the determination is made by setting the change form of the valid change, if it is determined that the change that has occurred is a deletion and insertion, the change can be regarded as a valid change, and so on.
All valid changes are divided into three classes, namely function changes, class variable changes and annotation changes. The specific classification of each valid change can be determined based on the location of the change.
And acquiring a first class of change functions according to the change of the function, wherein the first class of change functions comprise all change types which are the change functions of the function. And determining a list of affected change functions by analyzing the scope of the changed class variable according to the change of the class variable, namely obtaining the second class change function. And determining the affected change function list by analyzing the scope of the annotation according to the change of the annotation, namely obtaining the third type of change function.

On the basis of the above embodiment, in the embodiment of the present invention, the effective alteration function is obtained by removing duplication after merging the first type alteration function, the second type alteration function, and the third type alteration function, so that the efficiency of the regression test is further improved.
Further, based on the above embodiment, the obtaining, based on the effective changing function, a calling function that directly and indirectly calls the effective changing function specifically includes: based on the effective change function, acquiring the call function for directly and indirectly calling the effective change function by constructing a function call relation multi-branch tree; the function call relation multi-way tree comprises the effective change function and the call function.
And acquiring the calling functions for directly and indirectly calling the effective changing functions by constructing a function calling relation multi-branch tree based on the effective changing functions. For example, the direct call functions F1 to Fn that effectively change the function P are represented by P ═ { F1, F2, F3 … Fn }, and then the direct call function of each Fn is circularly analyzed, and finally a function call relation multi-way tree is formed. In the function-call relation multi-way tree, a function for directly calling the effective alteration function P and a function for indirectly calling the effective alteration function P together constitute a call function for the effective alteration function P.
Wherein the function call relation multi-way tree includes the effective change function and the call function.
On the basis of the embodiment, the embodiment of the invention acquires the calling function for directly and indirectly calling the effective change function by constructing the function calling relation multi-branch tree, thereby ensuring the comprehensive acquisition of the calling function and improving the accuracy of the regression test.
Further, based on the above embodiment, the determining a change interface function list according to all the effective change functions and all the call functions specifically includes: comparing the effective change function and the call function in the function call relation multi-branch tree with an interface function list determined under the current micro service item by traversing the function call relation multi-branch tree to obtain an interface function in each function call relation multi-branch tree; and the collection of the interface functions in all the function call relation multi-way trees forms the change interface function list.
Under the micro-service framework, all interface functions of the current software project and function paths corresponding to the interface functions can be accurately output. Because the interface function needs to be packaged into a library, the function path corresponding to the interface function is used for analyzing the calling relationship of the interface function. The main objective of the embodiment of the present invention to determine the accurate regression test range is to determine the interface function affected by the code change, i.e., the change interface function.
Since all interface functions of the current software project can be known, after the function call relation multi-branch tree corresponding to each effective change function is obtained, the effective change functions and the call functions in the function call relation multi-branch tree are compared with an interface function list determined under the current micro service project by traversing the function call relation multi-branch tree to obtain the interface functions in each function call relation multi-branch tree; one or more interface functions in each function call relation multi-branch tree; and the collection of the interface functions in all the function call relation multi-way trees forms the change interface function list.

And if the test points which completely complete the regression test do not exist, giving corresponding prompt information, wherein the prompt information comprises unfinished contents so as to prompt further regression test. And if the whole contents of the regression test are completely finished, giving a message of successful test.
It can be understood that, in order to evaluate the test result after the test is completed, the test content needs to be tracked and recorded in real time during the test process.
On the basis of the above embodiment, in the embodiment of the present invention, after the regression test is performed according to the regression test range, whether the regression test covers the regression test range is evaluated, and an evaluation result is given, so that the reliability of the regression test is improved.

Wherein the change of the variable and the annotation can determine the list of affected java functions by analyzing the scope of the change. And finally summarizing all java function lists influenced by effective changes to determine the java function list of the change.
