Playwright

What is Playwright and Why Should You Care

Why Playwright has become the go-to tool for modern web testing — and what makes it different from the rest

Installation & Your First Test

Set up Playwright from scratch and write a real test against SauceDemo

Debugging & Selector Tools

Playwright Inspector, codegen, the UI Mode locator picker, and the CLI flags that actually matter when a test won't cooperate

Selectors — Finding Elements the Right Way

data-testid vs ARIA roles vs CSS — a practical strategy that won't break when the UI changes

Assertions — Testing What Actually Matters

How to write assertions that catch real bugs without producing false failures

Page Object Model

Structure your test suite so it doesn't collapse the moment the UI changes

Advanced — How Playwright Works

What actually happens when you run npx playwright test — the test runner, workers, hooks, and the browser lifecycle

Tabs & Dialogs

Handling new tabs, popup windows, and native browser dialogs (alert/confirm/prompt) in Playwright

Frames & File Transfers

Interacting with iframe content, capturing file downloads, and uploading files in Playwright

Handling Flaky Tests

Diagnose and fix the intermittent failures that make your test suite unreliable

Reporting & Artifacts

Allure integration, custom reporters, and getting real value out of traces, screenshots, and video instead of just collecting them

CI/CD — Running Tests on Every Push

Set up GitHub Actions to run your Playwright tests automatically with reports, artifacts, and smart failure handling
