A robot that tests every push.

Continuous integration (CI) runs your tests automatically every time code is pushed. GitHub Actions does this with a small settings file.

The Whole Thing

# .github/workflows/test.yml
on: [push, pull_request]
jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v7
      - run: npm ci
      - run: npm test

What it gives you

Tests run even when you forget.

A green tick or red cross on every pull request.

Problems caught before they reach main.

Ask the agent to set it up for you.

Red means stop. Even on a Friday.
