End-to-End Testing with Playwright
Set up end-to-end tests to simulate user interactions across your entire application flow.
What is End-to-End Testing?
End-to-End (E2E) testing simulates a real user's journey through your application, from start to finish. It tests the entire stack: frontend, backend, and database.
Think of it as a robot user interacting with your app in a browser. This ensures all parts of your system work together as expected, catching issues that unit or integration tests might miss.
Why Playwright for E2E?
Playwright is a powerful open-source tool by Microsoft designed for reliable E2E testing. It offers several key advantages:
- Cross-browser: Tests Chromium, Firefox, and WebKit (Safari).
- Auto-wait: Automatically waits for elements to be ready, reducing flakiness.
- Robust actions: Simulates real user interactions like clicks, fills, and key presses.
- Fast & parallel: Can run tests across multiple browsers simultaneously.
