Test case priority determination method based on intelligent water drops in software regression test process

The invention discloses an intelligent water drop-based test case priority determination method in a software regression test process. The method comprises the steps of determining factors influencingtest case priorities; determining the importance degree of the test case according to the severity of the defects found by the test case; establishing a test case node selection rule according to theimportance degree of the test case; establishing an intelligent water drop speed updating rule according to the number of defects which can be found by the test case and the execution time of the test case; establishing a use case selection path soil amount updating rule; and after iteration of all the intelligent water drops is completed, determining priority ranking of the test cases in all theintelligent water drops. According to the method, the factors influencing the priorities of the test cases are fully considered, the problems that the factors influencing the priorities of the test cases are single and the fac
