Test Prioritization
Test prioritization is a software testing technique that ranks test cases based on their importance, risk, or business value to determine the order of execution. It helps optimize testing efforts by focusing on critical tests first, especially when time or resources are limited. This approach ensures that high-impact defects are identified early, improving software quality and release confidence.
Developers should use test prioritization in agile or continuous integration environments where rapid feedback is essential, or when dealing with large test suites that cannot be fully executed due to constraints. It is crucial for risk-based testing, regression testing, and in scenarios like tight deadlines or resource shortages to maximize defect detection efficiency and reduce testing costs.
