Boundary Value Testing Method and System in Structure Testing

Abstract

The invention relates to a boundary value testing method and system in structure tests. The method includes 1, selecting special boundary covering rules according to the semantic of statements and expressions in tested files; 2, acquiring a statement boundary value and expression boundary value of the tested files according to the special boundary covering rules; 3, select corresponding feasible paths for the statement boundary value and expression boundary value; 4, generating test cases according to the feasible paths, comparing the test cases, and acquiring boundary value testing results accordingly. According to the boundary value testing method and system in the structure tests, the special boundary covering rules are selected according to different statements and expressions, the corresponding boundary values can be found rapidly, and the boundary values of the statements and expressions in the structure tests can be tested.

Description

technical field [0001] The invention relates to the technical field of software testing, in particular, to a boundary value testing method in structural testing. Background technique [0002] Boundary value testing is proposed for functional testing. In 1979, Myers GJ. proposed that the boundary of the input domain is more error-prone than the middle, so the boundary value analysis is regarded as a test case generation technology that supplements the division of equivalence classes, that is, instead of selecting any element of the equivalence class, it is to select Price class boundaries. In 1997, Reid used 17 modules in real projects to conduct experiments to compare the error detection effects of boundary value, statement coverage, branch coverage, random and other testing methods. Experimental results show that Boundary Value outperforms all other methods, finding almost all bugs in 17 modules; for 14 of them, 50,000 random test cases are needed to get a test effect com...

However, these traditional coverage testing techniques are all based on the control flow graph, and the points and edges on the control flow graph are the coverage elements, so it is only required to generate a test case for the coverage element, regardless of whether the value is on the boundary, It is difficult for traditional coverage testing to detect errors in boundary values
