If you manage Linux servers and write automation scripts, you need unit tests — and Jest is the tool to get it done.

Why This Course Exists

Most testing tutorials teach you to test React components or web apps. But what about the scripts that provision your servers, manage your firewall rules, or rotate your SSL certificates? Those need tests too — and the patterns are completely different.

Jest Testing for Linux Admins covers:

✅ Mocking child_process.exec, spawn, and execSync for safe command testing

✅ Simulating filesystem operations without touching real files

✅ Snapshot testing nginx configs, SSH settings, and iptables rules

✅ Testing async operations — streams, event emitters, and concurrent processes

✅ CI/CD pipeline integration with GitHub Actions, GitLab CI, and Jenkins

✅ A capstone project building a complete test suite for a server provisioning script
