Abstract

The invention relates to a test program plagiarism detection method based on test code fragment similarity. The test program plagiarism detection method comprises the following steps: for each to-be-tested method in a to-be-tested program, firstly, calculating a unique method identifier based on a class name, a method name and a parameter sequence; secondly, extracting all test code fragment setsfrom the test program, wherein each test fragment corresponds to one to-be-tested method; then, analyzing the similarity between the test fragments to obtain a similarity analysis report, and calculating a similarity value between the fragments; and finally, calculating the overall similarity degree value of the test programs by utilizing the similarity value of the test fragments, and judging theplagiarism condition between the test programs more accurately by utilizing the overall similarity degree value of the test programs. The test program plagiarism detection method aims to fill the blank of a test code similarity detection technology, and solves the problems of low precision of test code similarity analysis and low efficiency of test code plagiarism detection mainly depending on manual operation at present, thereby improving the efficiency and precision of test code similarity detection.

Description

technical field [0001] The invention belongs to the field of software testing and code similarity detection, is especially suitable for the field of software testing code plagiarism detection, and solves the problem of difficult detection of plagiarism between test codes submitted by developers and testers in software testing competitions. By detecting the similarity of the test code fragments more accurately, it is possible to judge the overall degree of plagiarism between the test programs, avoid time-consuming and labor-intensive manual detection operations, and improve the efficiency and accuracy of test code plagiarism detection. Background technique [0002] Copying and pasting source code is a common activity in software engineering. Copying and pasting code can be both beneficial and harmful. On the one hand, software reuse can quickly improve coding efficiency, which is a view that most software developers agree with. Therefore, in the process of software developm...
