Understanding YAML for GitHub Actions and Running tests
Want to finally understand YAML and how it powers GitHub Actions? In this video, we’re breaking down the YAML syntax used in workflows — with a real-world demo running automated tests using npm install and npm test.
👨💻 First, we’ll run the tests locally in the terminal to show how it works on your machine.
⚙️ Then, we’ll create a GitHub Actions workflow that runs the same tests automatically when you push code — giving you a powerful intro to CI/CD!
✅ Perfect for JavaScript/Node.js projects, but the YAML principles apply to any language!
