Selective retest strategies can prove more cost-effective than a complete “retest-all” approach. How many selective retest strategies exist?
Show answer Hide answer
Answer: B. three
Explanation
Three primary selective retest strategies exist to optimize regression testing time and computational costs. These strategies include minimization, safe approaches, and coverage-based test selection methodologies. Selecting a subset of tests reduces execution time while maintaining high defect detection confidence. Regression test selection aims to choose relevant test cases without running an entire test suite. Minimization strategies select a minimal subset of tests that cover modified program components. Safe retest strategies guarantee that all tests capable of revealing modified faults are included.
Large software projects with massive test suites rely on selective retest strategies to save time. Continuous deployment pipelines use coverage-based retest selection to speed up build verification. Software testing researchers continuously develop advanced algorithms to improve retest selection precision. Two strategies do not cover the full range of minimization, safe, and coverage-based approaches. Four strategies exceed the recognized taxonomy of selective regression testing methodologies. Five strategies misrepresent the standard classification used in software testing literature.
