Embodiment 1

[0033] Embodiment 1: a kind of regression test case selection method based on improved harmony search algorithm mainly comprises the following steps:

[0034] The first step: obtain the information of the test case, at least obtain the information of each test case coverage function: in the present invention, the necessary information of the test case is obtained by means of source code insertion.

[0035] Before testing, first perform source code instrumentation on the modified program to be tested. The stub probe inserted into the source code is responsible for collecting test case information, and storing the captured test case execution path, execution time and other relevant information in the database. These actual running information create conditions for the optimal selection and coverage analysis of test cases. On the basis of source code instrumentation, the entry of test cases can be completed by running the test cases in the original baseline test case library T0....

Abstract

The invention discloses a regression test case selection method based on an improved harmony search algorithm. The regression test case selection method includes the steps: firstly, screening a test case of a sensitivity function covering modification from a selected test case set; secondly, selecting a proper case selection mathematical model according to the selected test case; thirdly, optimally selecting the test case by the improved harmony search algorithm with an excellent harmony element database EEL. The excellent harmony element database EEL is updated once every a certain search algebra and stores excellent harmony elements, and the excellent harmony elements include intersection of sets comprising overall goal optimal harmony elements and suboptimal harmony elements, and intersection of sets comprising sub-goal optimal harmony elements and suboptimal harmony elements.

Description

technical field [0001] The invention relates to a method for selecting a use case in a regression test, in particular to a method for selecting a use case for a regression test based on an improved harmony search algorithm. Involving patent classification number G06 calculation; calculation; counting G06F electrical digital data processing G06F11 / 00 error detection; error correction; monitoring G06F11 / 36 preventing errors through software testing or debugging. Background technique [0002] Regression testing refers to retesting after modification of existing software to confirm that the modification does not introduce new errors or have side effects on existing unmodified modules. As an important part of the software life cycle, regression testing occupies a considerable proportion in the entire software testing work, and is of great significance to ensure software quality. [0003] In the software life cycle, in order to fix software errors or respond to changes in custome...
