Multifactor Weighted Approach (MFWA) using six factors to calculate the priority value which are complexity, redundancy, frequency, permutations and fault matrix. The factors are chosen based on the characteristics of event sequence with the purpose to obtain a unique prority value. However, if same priority value exists, Jacard Distance approach will be used to break the ties. The invention aims to prioritize event-sequence test cases in a test suite in order to allow earlier detection of faults as well reduce time, cost and efforts. Automate the process of selecting test cases that managed to detect faults earlier besides reduce time, cost, and resources during the testing process. Useful for test case prioritization or software testing domain.
