Automated Testing in Pipelines

Summary

Running unit, integration, or other tests automatically as part of the pipeline, and failing the build if they don't pass — the mechanism that actually gives CI its safety net.

• 1Add an automated test step to a CI pipeline and confirm it fails the build on a broken test.
• 2Learn the difference between fast unit tests (run on every commit) and slower integration tests.
• 3Understand why a pipeline without meaningful tests provides a false sense of safety.
