What is a test suite?

A test suite is an organized collection of test cases or automated specs run together for a purpose - smoke, regression, nightly, or release candidate. Suites are grouped by risk, speed, or feature area so pipelines can run the right set at the right time. A “full regression suite” might take hours; a “smoke suite” might finish in minutes on every build. Naming and ownership matter: unclear suites become dumping grounds for obsolete tests. Suite health metrics include pass rate, duration, flake rate, and coverage of critical journeys. Refactor suites as the product changes - delete or quarantine tests that no longer map to real user value. One well-curated suite beats a large unmaintained catalog.
