Measuring test suite reusability based on the usage frequency and coverage of reused test cases

Test suite reusability measurement is important to obtain the value of reusability as the degree of effectiveness of reused test suite. The measurement in this experiment considers not only the frequency of the successful test suite to examine different objects but also the code coverage as the criteria of a good test suite. The combination of the frequency and code coverage in the measurement reports the current condition of test suite reusability. The research confirms the test suite reusability measurement provides useful information to know the degree of effectiveness of reused test suite, especially in regression testing and automated testing.
