Abstract

The method comprises the steps of dividing a system to be tested into different functional modules, determining weights of the functional modules, designing basic test cases for the functional modules, automatically executing the test cases, recording the defect number of the functional modules and the test case number, calculating defect density and risk index of the functional modules, supplementing the test cases for the functional modules with the risk index higher than a threshold value, and performing iterative optimization. The embodiment uses a data analysis technology to identify a system key test module, focuses test resources on the key test of the key module, and supplements test cases in a targeted manner by analyzing historical case execution conditions and defect data to construct a dynamic test case set, thereby effectively solving the contradiction between quality and efficiency in agile test. On the premise of ensuring the defect detection rate, the concentrated test resources are used for carrying out the key test on the key module, so that the test resources are redistributed, and the test efficiency and the defect detection capability are obviously improved.
