Running and Testing GitHub Actions Locally and in CI

Question: Run github actions locally

You can run GitHub Actions locally using the act tool. This helps test workflows before pushing to GitHub.

Steps:

1. Install act:

   brew install act

2. Run your actions:

   act

3. Simulate different events:

   act push
   act pull_request

Tips:

• Docker is required.
• Use --platform if needed.

Question: Set github actions with bun

Bun can be used as the runtime in your GitHub Actions workflow by configuring the action to use a setup step like:

- uses: oven-sh/setup-bun@v1
  with:
    bun-version: "latest"

Tips:

• Replace node scripts with bun commands for compatibility.

Question: Whats the best way to run e2e test of a webapp in github actions

Use a headless browser like Chrome and a test runner like Puppeteer or Playwright.

Sample GitHub Action step:

- name: Run e2e tests
  run: bun test:e2e

Tips:

• Install dependencies before testing.
• Ensure the server is running or mocked.

Question: Give me for puppeteer

To run Puppeteer tests:

1. Install Puppeteer:

   bun add puppeteer

2. Create a test:

   const browser = await puppeteer.launch();
   const page = await browser.newPage();
   await page.goto("http://localhost:3000");

3. Run in CI with xvfb or headless mode.

Tips:

• Set PUPPETEER_SKIP_CHROMIUM_DOWNLOAD=true to speed up CI builds.
