What is Playwright?

Playwright is a browser automation library developed by Microsoft that lets you control Chromium, Firefox, and WebKit with a single API. It is ideal for cross-browser testing.

Unlike Puppeteer, Playwright supports multiple browsers by default and enables you to write more reliable tests.

Core Features

Playwright offers powerful features like auto-waiting, network interception, mobile emulation, and visual comparison. The auto-wait mechanism waits until elements are ready for interaction.

You can also use the Codegen tool to record browser interactions and generate automated test code.

Writing Tests

Writing tests with Playwright Test is straightforward. A simple test scenario involves opening a page and interacting with elements.

page.goto() for page navigation page.locator() for element selection page.click() and page.fill() for interaction expect() for assertions

Visual Testing

Playwright enables you to detect UI regressions with visual snapshot comparisons. You can take a screenshot of a page and compare it to a reference image.

CI/CD Integration

Playwright tests integrate easily with GitHub Actions, Jenkins, and other CI/CD tools. Docker support ensures consistent test environments.
