What is Playwright?

Playwright is a Node.js library developed by Microsoft that enables reliable browser automation across multiple browsers, including Chromium, Firefox, and WebKit. It is designed for end-to-end testing, allowing developers to automate interactions with web applications stably and efficiently. Playwright provides built-in support for modern web features such as network interception, mobile emulation, and advanced debugging. It is widely used in test automation due to its flexibility, robust API, and ability to work across different operating systems and platforms.

Playwright supports multiple programming languages, including JavaScript, TypeScript, Python, C#, and Java, making it accessible to a broad range of developers. It allows writing scalable and maintainable test scripts while ensuring compatibility with various browsers and devices.

Why Use Playwright?

●       Cross-browser support: Works with Chrome, Firefox, Edge, and Safari

●       Headless mode: Enables faster test execution by running tests without a graphical interface

●       Multi-language support: Compatible with JavaScript, TypeScript, Python, C#, and Java

●       Parallel execution: Runs multiple tests simultaneously to reduce execution time

●       Mobile and device emulation: Simulates different screen sizes and device environments for responsive testing

●       Network interception: Allows mocking API responses and modifying network traffic during tests
