Unit tests all green, but QA finds a bug in three clicks. That's the E2E gap. Here's everything you need to automate real browser scenarios with Playwright — from first test to CI integration.

Unit tests check the bricks; E2E tests check the building. Learn how to simulate real user journeys using modern tools like Cypress and Playwright. We cover best practices for writing resilient selectors, handling authentication, fighting test flakiness, and where E2E fits in the Testing Pyramid.
