Coverage measurement experience during function test

The authors discuss the issues of test coverage measurement in industry and justify the benefits of the measurement using a framework developed by them. Some results of experiences using test coverage measurement are outlined. The function test of large-scale system software is defined and analyzed. Based on the discussions of function test, a framework for analyzing the function test error removal process is developed. An experience-based error removal model and a cost model are proven to be useful tools for justifying test coverage measurement during function test. Data obtained from a real project are analyzed using the framework for validation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
