CI Verification Skill
This skill provides the necessary commands and context to verify your changes locally, matching the checks performed by the GitHub Actions CI pipeline in .github/workflows/ci.yml.
Verification Pipeline
Before submitting a pull request, ensure all the following checks pass.
1. Setup Environment
Ensure your local environment is correctly set up.
make setup
2. Linting
Runs Prettier, ESLint, and Lit-analyzer to check code style and common issues.
make lint
3. Type Checking (Python)
Runs mypy for static type analysis of Python code.
make mypy
4. Backend Tests (Python)
Runs Python unit tests using the Datastore emulator.
npm test
5. Frontend Tests (Lit/Playwright)
Runs web component tests using Playwright.
make webtest
6. Build Assets
Verifies that all assets (JS, CSS, etc.) build correctly.
make build
Summary Command
To run the most critical local checks (test, webtest, lint, mypy) in one go:
make presubmit
Reference
- Build Targets: @Makefile
- Task Scripts: Defined in @package.json.
