Playwright is an open-source automation library developed by Microsoft for end-to-end testing of web applications. It enables developers and testers to simulate browser interactions (like a real user) by automating tasks such as navigating web pages, filling out forms, clicking buttons, taking screenshots, and performing complex workflows.
Playwright is designed to be reliable and fast, supporting multiple browsers (Chromium, Firefox, WebKit) with a single API. It can run tests in headless mode (without opening a graphical browser window) and headful mode (with a visible browser). Playwright also supports testing across various platforms (Windows, Linux, macOS) and can emulate mobile devices.
Some key features of Playwright include:
- Cross-browser testing
- Support for multiple languages (JavaScript, TypeScript, Python, C#)
- Built-in support for capturing and replaying network activity
- Automatic waiting for elements to be ready before performing actions
Playwright is commonly used for automated functional testing, regression testing, and performance testing in modern web development.
