Automation Testing with Playwright

Playwright is a powerful open-source framework for web automation and testing. It supports multiple browsers and provides a unified API for creating robust, reliable automated tests. Playwright uses a unique architecture that allows it to control browsers at a low level. It launches browsers in a special “headless” mode by default, which runs without a visible UI. This approach enables faster test execution and better integration with CI/CD pipelines. In this article, we will explore the prerequisites, steps to get started with Playwright, and how to run our first test case.

Key Features

1. Cross-browser support (Chromium, Firefox, WebKit)
2. Auto-wait functionality
3. Network interception and mocking
4. Multiple language bindings (JavaScript, TypeScript, Python,?.NET)
5. Parallel test execution
