Playwright & Modern Web Automation

Build browser automation that doesn’t flake.

Technical guides for reliable Playwright automation: setup architecture, selector strategies, advanced interactions, and CI-ready debugging workflows. Every guide is written for engineers who ship: concrete TypeScript you can paste into a real suite, the failure modes behind each technique, and how it behaves under parallel, headless CI.

Start with a top-level guide for the mental model, drop into a technique area for the API surface, or jump straight to a deep dive when you have a specific problem to fix. Everything below is one click away.

Start here

The pages engineers reach for first — the mental models that make everything else easier, and the topics that cause the most support tickets.

getByRole & Accessibility Selectors

The single change that removes most selector flakiness. Start here if tests break on every refactor.

Authentication & Session State

Log in once, reuse the session everywhere, and keep parallel workers from stepping on each other.

Web-First Assertions

Why web-first assertions retry for you, and how to stop writing manual waits.

Trace Viewer & Debugging

Diagnose a CI-only failure from the trace instead of re-running the suite to reproduce it.

Iframes & Embedded Content

Frame locators, cross-origin limits, and the third-party payment widgets everyone gets stuck on.

Visual Regression Testing

Screenshot baselines that survive a font-rendering difference between your laptop and CI.
