However, all the algorithms proposed so far are to firstly cover the combination space in the t dimension, and each time the full coverage is reached, the coverage of the combination space is blanked out, and the process of covering the combination space is restarted, that is, lost The information covered before is combined, so the optimized test case set obtained each time is only a local optimal solution rather than a global optimal solution

[0049] Usually, n-dimensional parameter combinations are also called n-level patterns, and n is called the size of the combination. Likewise, if a combination of n-dimensional parameters satisfies all constraints (C), the test case is valid. When η=k, n-dimensional parameter combinations are (potential) test cases for the SUT. Test case tc=(l 1 , l 2 ,...,l k ) can cover the n-dimensional parameter combination φ=((l' i1 ,l' i2 ,...l′ iη ), where l' represents a specific parameter, if and only if for 1≤j≤η,l ij = l i ' j , the parameter f ij in tc and is the same in . Obviously, each test case can cover C(k,η)n-dimensional parameter combinations. For ease of description, we define CombSet(η, tc) as the combination of n-dimensional parameters covered by test case tc; and CombSet(η, T) as the set of combinations of n-dimensional parameters covered by all test cases in T, namely CombSet (η,T)=U tc∈T CombSet(η,tc).

Abstract

The present invention discloses a method and system for prioritizing and sorting combined test case sets based on weight, comprising the following steps: Step 1, according to the parameter set of the program to be tested, the range of combined coverage t is determined, and the test case is generated based on the combined coverage t The t-dimensional combination of the test program is defined as set A; step 2, the test case set of the test program is prioritized and sorted, and the time cost of optimizing the entire test case set and the average time cost after running 200 times are recorded, and the results are The set and time overhead are output in the form of files; step 3, conduct simulation experiments on the obtained optimized test case set to test the program, and record its error detection rate. On the premise of ensuring the time overhead, the present invention enables the obtained optimized test case set to have a better error detection rate in the simulation experiment, thereby reducing the time cost required in the test stage in the actual test and improving the test efficiency.

Description

technical field [0001] The invention belongs to the field of software testing, and relates to a method for prioritizing and sorting combined test case sets based on weight (FICBPW), which optimizes and sorts test case sets to be sorted. Background technique [0002] At present, the rapid development of computer technology promotes the development of all walks of life in society, ranging from the development of national economy and culture to the progress of daily life. However, as people's demand for software systems increases day by day, and the scale of computer software systems continues to grow, software failures or failures in software systems also occur, and the importance of software testing is gradually revealed. [0003] With the diversification and complexity of the functions of the software system, many factors may affect the behavior of the software system, and these factors are collectively called parameters. At the same time, these parameters have some optiona...
