Embodiment Construction

[0041] Such as figure 1 , the present invention combines the evolution information of the software and the improved beetle-beetle search algorithm to amplify the regression test case set, and the pre-processing part adopts the method call diagram of the program and the method coverage execution information to obtain the ordered target method set and the initial test case In the later stage, the optimization algorithm is used to amplify the regression test data. The specific steps are as follows:

[0042] (1) The method call diagram generated by the Doxygen tool for the Java program is as follows figure 2 shown;

[0043] (2) Using the original test set t 1 =(-2,1,4),t 2 =(1,2,3),t 3 =(3,4,5),t 4 =(3,3,4) and the method call track to establish program execution information, the old and new versions of the program execution information are represented by matrix A and A', where f 1 → main() {}, f 2 → getType(triangle) {}, f 3 → judgeType() {}, f 4 →isTriangle(triangle){}...

Abstract

The invention discloses a software test data set amplification method based on beetle antennae search, and belongs to the field of software regression testing. Aiming at the problem that an original test case is difficult to meet the test requirement of a modified new program caused by software evolution, the invention provides a test case amplification method based on program execution information and beetle antennae search. The method includes: statically analyzing new and old version programs, obtaining a method call graph and program execution information, obtaining a target method set needing to be tested, and sorting the target methods by calculating the influence degree of errors contained in the methods; according to the method coverage information of an original test case set, selecting part of test cases as an initial population, designing a fitness function through branch distances and branch nesting depths, and adopting an improved beetle antennae search algorithm to perform test data amplification on an ordered target method set. According to the method, the method call graph, the program execution information and the beetle antennae search algorithm are utilized to amplify regression test data, the utilization rate of an original test case is increased, and the regression test cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of software testing, especially in the technical field of regression testing. It is used for expanding test data sets and fully utilizes the original test sets to meet the testing requirements in the process of software evolution. It is a software testing data set amplification method. . Background technique [0002] In the process of software product development and maintenance, software evolution behavior will be triggered by code modification. In order to effectively guarantee the quality of the modified software product, regression testing is generally performed to ensure the correctness of the code modification module and avoid the code modification module from affecting the program under test. Side effects produced by other modules. Regression testing refers to retesting the evolved software after modifying the existing software to confirm that the newly introduced modification does not introduce new ...
