Playwright automates UI testing by controlling a browser to navigate pages, click elements, fill forms, and verify results. Install Playwright via npm, write tests in TypeScript or JavaScript that interact with your local web app, and run them with npx playwright test to validate frontend functionality end-to-end.

Yes. Playwright supports clicking buttons, typing into form fields, selecting dropdowns, and waiting for elements to appear or change. You can assert on text, visibility, and attributes, then screenshot or log results to verify that user interactions produce expected UI changes.

Playwright lets you intercept network calls and capture console output during tests. Listen to console events and network responses in your test code, log them for inspection, and use screenshots to visually confirm UI state at each step, enabling rapid diagnosis of frontend bugs.

Yes. Playwright tests run in development, staging, and CI environments using Node.js and npm. Structure reproducible end-to-end workflows that spin up your local app, run the test suite with npx playwright test, and report results, integrating easily into automated deployment pipelines.

No. Playwright provides common actions—navigation, clicking, form input, waiting—with simple, readable syntax. Write tests as normal TypeScript or JavaScript files, and the toolkit handles browser automation, so you focus on describing what the UI should do.

Playwright tests local web apps in a browser context, so they cannot directly test backend logic, database queries, or server-side code. They also require a running application instance and may be slower than unit tests; use them alongside unit and integration tests for comprehensive coverage.
