Smoke Test - CI/CD Glossary Definition
A smoke test is a quick, shallow check that the most critical functionality works at all, run right after a build or deploy. The name comes from hardware: power it on and see if it smokes.
Why it matters
A post-deploy smoke test catches gross failures (the app will not start, the homepage 500s) in seconds, before a fuller test suite or real users hit the new version. It is a common deployment gate.
