GitHub Actions - Automate Testing & Deployment in Git & GitHub

GitHub Actions automatically runs tests, linters, and deployments when code is pushed or a PR is opened. This ensures quality without manual work. For example, every PR is tested before merge.

Workflows are defined in `.github/workflows/*.yml` files. A simple workflow might: install dependencies, run tests, lint code, and report results.

Priya and Arjun add a workflow that runs tests on every PR. If tests fail, the PR can't be merged. This prevents broken code from reaching main.
