[0046] The first thing to say is that metamorphic testing is a technique for alleviating the problem of testing expectations. This technology utilizes certain intrinsic properties (transformation properties) of the program to be tested to generate test cases (including original test cases and derived test cases), and then executes the original test cases and derived test cases to obtain corresponding outputs. By verifying whether the output satisfies A certain relationship (transformation relationship) is used to judge the test results. Metamorphic testing technology does not need to know the expected output corresponding to each test case, which can effectively alleviate the problem of test expectations.

[0047] Based on the above, aiming at the test expectation problem in the concurrent program testing process, this embodiment provides a concurrent program metamorphosis testing method, which can be implemented by an electronic device, and the electronic device can be a term...

Abstract

The invention discloses a metamorphic test method for a concurrent program in order to solve the test expectation problem existing in a concurrent program test, and the metamorphic test method comprises the following steps: aiming at the characteristic of executing interlacing by the concurrent program, guiding the identification of a metamorphic relation mode by using an interlacing scene capable of triggering data competition; taking the execution track of the original test case as an original execution sequence, generating a derivative test case according to the metamorphic relation mode, and controlling the execution of the derivative test case; verifying the test result by comparing whether the output results of the derivative test case and the original test case violate the current metamorphic relation mode or not; meanwhile, a metamorphic relation mode of concurrent programs is provided, and generation of derivative test cases and judgment of test results are guided. According to the method, the execution process of the program is optimized by reducing the interlaced space of the concurrent program, and the data competition fault in the concurrent program can be effectively detected.

Description

technical field [0001] The invention relates to the technical field of software testing, in particular to a method for metamorphosis testing of concurrent programs. Background technique [0002] Concurrent programs have multiple concurrently executing processes, and the processes usually share some storage space explicitly or implicitly, and their execution order is uncertain. The situation of non-deterministic interactions and influences between concurrent processes is often referred to simply as execution interleaving. Execution interleaving not only easily leads to the introduction of new defects in the design phase of concurrent programs, but also brings challenges to the analysis and testing of concurrent programs. How to effectively detect hidden defects in concurrent programs and improve the reliability of concurrent programs has become an important problem to be solved in the field of concurrent program development. [0003] Software testing is a widely used method...
