A comprehensive, self-contained guide to Playwright — the modern framework (from Microsoft) for driving real browsers through code.

Welcome to Playwright: Modern Browser Automation for Testing and Scraping.

A comprehensive, self-contained guide to Playwright — the modern framework (from Microsoft) for driving real browsers through code. Like Selenium, it launches Chromium, Firefox, and WebKit, navigates pages, runs their JavaScript, clicks and types, and reads the rendered result — for two big jobs: automated end-to-end testing and scraping JavaScript-rendered pages. But Playwright was designed after Selenium, learning from its pain points: it auto-waits for elements (eliminating most flaky-test bugs), drives all major engines through one API, intercepts and mocks network traffic, and ships a first-class test runner, codegen, and trace viewer. This book teaches it end to end — the browser/context/page model, locators, actions and auto-waiting, web-first assertions, network interception, real-world page handling, scraping, the test runner, and debugging/CI — blending intuition, the concepts behind the framework, and runnable code.

This title is part of the ShriIra library and is free to read in full, right here — our small contribution to making world-class knowledge easy to reach.
