End-to-end testing with Playwright involves installing the framework, configuring playwright.config.ts with your browsers (Chromium, Firefox, WebKit), placing tests in the e2e/ directory, and running npx playwright test. This automates validation of complete user flows across your web application.

Yes, Playwright supports multi-browser testing across Chromium, Firefox, WebKit, and mobile emulations in a single test suite. Configure your playwright.config.ts to define projects for each browser, and tests run against all simultaneously in CI/CD pipelines.

The Page Object Model is a design pattern that encapsulates page elements and interactions into reusable classes, reducing test maintenance. It improves readability, isolates UI changes to a single location, and scales well as your Playwright test suite grows across multiple user flows.

Visual regression testing in Playwright captures baseline screenshots and compares subsequent test runs pixel-by-pixel to detect unintended UI drift. Integrate screenshot snapshots into your test assertions and CI/CD pipeline to automatically flag visual regressions.

Playwright integrates natively with CI/CD systems through command-line execution and generates detailed reports, traces, and screenshots. Run npx playwright test in your pipeline to automate cross-browser end-to-end tests on every commit or deployment.

Playwright supports testing authentication flows by simulating login interactions, managing session state, and validating protected user journeys. Use page navigation, form filling, and cookies to replicate real authentication scenarios end-to-end across your application.
