Reliability is non-negotiable. We've completed a major migration of our End-to-End (E2E) testing infrastructure to use Vitest Browser Mode with Playwright.

Why the change? Previously, some component tests relied on mocking internal router hooks, which led to fragile tests that didn't reflect real user behavior. By shifting to a true browser-based approach, we solved 37 failing tests and gained significant confidence in our release pipeline.

The New Setup:

Real Browser Testing: Tests run in Chromium via Playwright, simulating actual user interactions.
No More Mocking Routers: We test the app exactly as it runs in production.
Enhanced DX: Developers can now use the Vitest UI to watch tests run in real-time.

This migration ensures that when all checks pass, the application really works for our users.
