Proposal of a Method to Measure Test Suite Quality Attributes for White-Box Testing

As an important asset in software testing, measuring quality attributes of the test suite is important to describe the quality of software. This research proposes a method to measure the test suite quality attributes for white-box testing. The attributes are usability, efficiency, reliability, functionality, portability, and maintainability that are selected from 28 attributes in software quality. By using the proposed method, the test suite quality attributes are calculated with various results of level of quality. The result of test suite quality attribute measurement then proves the validity of its result by the reliability analysis. It is used Cohen’s kappa coefficient to validating the result of test suite quality attributes measurement based on the level of agreement between the result of measurement and expert assessment. Reliability analysis on test suite quality attribute finds the attribute that strongly related based on the minimum percentage of level of agreement value are usability, reliability and functionality. Hence, our proposed method is useful to measure test suite quality attributes.
