In this paper, we described the regression testing of test case prioritization. Statistical analysis: To categorize the cruel mistakes and get better the rate of fault detection, test case prioritization algorithm is proposed. Result: It prioritizes the test cases depends on few sets of realistic load aspect such as: changes in requirements, traceability, completeness, developer observed code execution complexity, fault impact and customer allotted priority. Conclusion: The implementation of
