The present invention is based on the cluster filtering technology in the observed software testing technology, selects test cases in the cluster for verification, and calculates the credibility of the executed statements according to the verification results of the selected test cases. Pass, the statement is credible, otherwise it is suspicious; calculate the probability of failure of each remaining test case in the cluster according to the statement credibility. The test case with the highest probability, and then recalculate the credibility of each statement according to the verification result of the test case, and calculate the probability of failure of the remaining unverified test cases, and select the next test case; the whole sampling process is repeated in this way , until the failure probability of all remaining test cases in the cluster is 0, that is, the executed statements of the remaining test cases are all credible, then the test cases that have been sampled and ...
