Regression and smoke testing serve distinct purposes in development lifecycle¶
Insight: Smoke testing performs quick health checks on critical functionality immediately after builds, while regression testing validates comprehensive system stability after changes. The workflow sequence is strict: smoke testing gates whether the build is stable enough for deeper testing, then regression testing confirms no existing functionality broke.
Detail: Smoke testing typically completes in hours with limited scope, whereas regression testing requires significant time for full coverage. Developers typically run smoke tests before handing to QA; QA teams conduct regression testing. Automation accelerates both but particularly improves regression testing efficiency.
