Playwright Mastery Path¶
A structured, module-wise training program that takes you from launching your first browser to running a production-grade end-to-end test suite in CI — using Playwright's Python API (with JavaScript/TypeScript parity notes throughout, since most teams run both), with runnable code and a hands-on project at the end of each level.
How the program is organized¶
| Level | Focus | Modules |
|---|---|---|
| Level 1 · Entry | First scripts, locators, actions, assertions | 9 topics + 1 project |
| Level 2 · Intermediate | Page Object Model, fixtures, network mocking | 9 topics + 1 project |
| Level 3 · Advanced | Visual regression, auth reuse, API testing, CI | 9 topics + 1 project |
| Level 4 · Master | Cross-browser strategy, component testing, scale | 9 topics + 1 capstone |
Who this is for¶
- Manual testers and QA engineers moving into automated end-to-end testing.
- Developers who need reliable, fast E2E tests instead of flaky Selenium suites.
- Career changers starting from zero — Level 1 assumes no prior testing or Playwright experience, only basic Python.
Why Playwright¶
Playwright auto-waits for elements to be actionable before interacting with them, drives Chromium, Firefox and WebKit from one API, and ships a trace viewer that turns "why did this test fail in CI" from a guessing game into a recording you can scrub through frame by frame. It has become the default choice for new E2E suites over Selenium for exactly these reasons — you'll see each one justified with real code as you go.
How to use this site¶
- Work through each level in order — later modules assume earlier ones.
- Every module has runnable code — copy it into a local
.pyfile and run it withpytestor plain Python. - Each level ends with a project that combines everything learned in that level.
- Use the search bar (top of the page) to jump straight to a topic.
