Test coverage rate improving method and device, computer equipment and storage medium

Abstract

The invention relates to a test coverage rate improving method and device, computer equipment and a storage medium. The method comprises the steps of obtaining an original test case; obtaining online data; processing the online data, and importing the processed online data into an offline test environment to obtain an original test data set; generating a metamorphic test case according to the original test case, the original test data set and the metamorphic relationship; and performing a metamorphic test on the metamorphic test case to obtain a test result. According to the method, after the test model is constructed and the test case and the online data are obtained, the metamorphic test case is generated according to the set metamorphic relationship, and the test model is tested by utilizing the metamorphic test case, so whether the software test is qualified or not is judged, and more test data do not need to be manually obtained for model test; and the metamorphic test cases processed by adopting the metamorphic relationship can consider different test conditions to a greater extent, so the test cases are increased, and the test coverage rate and the working efficiency of testers are improved.

Description

technical field [0001] The invention relates to a computer, more specifically to a method, a device, a computer device and a storage medium for improving test coverage. Background technique [0002] The process of software development requires software testing steps. In the process of software testing, there must be test assertions to verify whether the software output conforms to the facts according to the expected value. Different test data may produce different results based on the behavioral drive of model-based testing. In this case, there are difficulties in how to prepare enough test data for data-driven testing and how to judge that the results are consistent with the expected value. [0003] At present, it is only possible to obtain more test cases by continuously increasing test data to achieve a more ideal test purpose, but this method is also difficult to achieve a greater degree of test coverage, and the test cases obtained are very limited. Cannot improve tes...
