Integrating customized test requirements with traditional requirements in web application testing

Existing test suite reduction techniques employed for testing web applications have either used traditional program coverage-based requirements or usage-based requirements. In this paper, we explore three different strategies to integrate the use of program coverage-based requirements and usage-based requirements in relation to test suite reduction for web applications. We investigate the use of usage-based test requirements for comparison of test suites that have been reduced based on program coverage-based test requirements. We examine the effectiveness of a test suite reduction process based on a combination of both usage-based and program coverage-based requirements. Finally, we modify a popular test suite reduction algorithm to replace part of its test selection process with selection based on usage-based test requirements. Our case study suggests that integrating program coverage-based and usage-based test requirements has a positive impact on the effectiveness of the resulting test suites.
