Experiments on Test Case Reuse of Test Coverage Criteria

Test cases of original program could be reused in order to reduce cost of testing the modified program. The reusability of test cases is affected by the rewriting skills and test coverage criteria which are adopted in rewriting and testing process of modified program. This paper summarizes frequent rewriting pattern in rewriting program, and analyzes the effect of them in testing modified program. Many substantial experimental works have been carried on three applications, and results State reusability of test case are related with rewriting pattern and test coverage criteria.
