1.5Hands-On Exercise

1. Pick the platform your team uses (or GitHub Actions if you are learning independently)
2. Create a pipeline that:
   • Triggers on push and pull request
   • Has two jobs: lint and test
   • The test job depends on lint passing
   • Uses caching for dependencies
   • Uploads test results as artifacts
3. Intentionally break a test and verify the pipeline fails and produces useful artifacts
4. Add a scheduled trigger for a nightly run

This exercise covers the fundamentals that apply to every platform. Once you have built one pipeline from scratch, the concepts transfer everywhere.
