Embodiment Construction

[0028] For the sake of reference and clarity, the technical terms, abbreviations or abbreviations used in the following text are summarized as follows:

[0029] Finite solution problem: If a function / program has a limited set of test cases to ensure that the logic can run normally, it is called a finite solution problem;

[0030] Non-infinite solution problem: If a function / program has an infinite set of test cases to ensure that the logic can run normally, it is called an infinite solution problem. In theory, an infinite solution problem cannot guarantee that the function / program will work in all cases normal.

[0031] In addition to poor pertinence, in traditional white-box testing, different inputs are likely to have different results for the same code execution (different results, corresponding logical exits or logical branches are also different), even for the same input, it may be due to Different states produce different results (different results correspond to differe...

Abstract

The embodiment of the invention discloses a program code testing method and device and aims at reducing massive detection brought by traditional route coverage and solving the problem that the detection has not pertinence. The program code testing method comprises the steps that the testing purpose of a test is obtained; a logic topological tree corresponding to a procedure code is searched to obtain a logic outlet node relevant to the testing purpose and serving as a target logic outlet node; the target logic outlet node is used as a starting point, and logic testing is conducted on a logic path containing the target logic outlet node in the logic topological tree. It is thus clear that in the embodiment, logic testing is conducted on a logic path containing the target logic outlet node relevant to the testing purpose, rather than logic testing conducted on all logic paths. Due to the fact that the test is the logic test based on the testing purpose, the program code testing scheme provided by the embodiment has more pertinence compared with traditional white box testing.

Description

technical field [0001] The present invention relates to the field of computer technology, more specifically, to a program code testing method and device. Background technique [0002] White box testing is also known as structural testing, transparent box testing, logic-driven testing or code-based testing. The box refers to the software (or program) under test, and the white box means that the box is visible, and it is clear what is inside the box and how it works. [0003] One of the coverage criteria of traditional white-box testing is logic coverage. Logic coverage includes statement coverage, decision coverage, condition coverage, decision / condition coverage, condition combination coverage and path coverage, and its ultimate goal is to execute all paths at least once. Such as figure 1 As shown in , the program code needs to go through the logic layer from the entry node to the exit node, and the logic coverage finally expects to cover all possible logic branches, and ...
