Smoke testing is one of the fastest ways to verify whether a new build is stable enough for further testing. It helps teams quickly detect critical issues like login failures, API crashes, broken deployments, or database connection problems before wasting QA effort on unstable builds. Modern DevOps teams heavily rely on smoke testing inside CI/CD pipelines for faster and safer releases.
