Playwright Browser Automation

Playwright automates browser testing by generating and executing scripts that interact with web pages. You describe what you want to test—login flows, form filling, link checks, or responsive design—and Playwright writes and runs the test script, displaying results in real time with a visible browser for easy debugging.

Yes. Playwright auto-detects running dev servers on your machine and automatically targets the correct local URL for testing. This eliminates manual server detection and lets you test your app during development without extra configuration.

Playwright writes all test scripts to /tmp with deterministic naming, keeping your project directory clean. Tests execute from there and return results immediately, so you get a clear separation between your source code and temporary test artifacts.

Playwright tests both local development servers and external sites. You can parameterize URLs via environment variables or script constants, making it flexible for testing your own applications, third-party services, or any publicly accessible web page.

Visible browser mode (headful) makes debugging step by step easier because you see exactly what the browser is doing as the test runs. This helps you catch UI issues, timing problems, and unexpected behavior faster than reading logs alone.
