# Angular Testing has finally evolved! 🥳

## 🧪 Vitest

With **Karma** being deprecated since 2023 and the **Angular framework recent evolution** (standalone, zoneless, ...), it was time for the tooling to evolve... and the Angular team has finally choosen **Vitest** as the new default testing framework!

Vitest brings a powerful API, a rich, forward-looking ecosystem that’s TypeScript-first and fully supports ESM (ECMAScript Modules). It also includes a browser mode, which means tests can run in a real browser environment.

Starting with **Angular 21** (expected in November), new projects will come with **vitest set-up out of the box**!

## 🚀 Testronaut

E2e testing is also getting some love!

**Testronaut** is a new tool for Angular **component testing**.  
It runs your components in a real browser, using Angular’s own build process.  
That means:

*   Components behave exactly as they do in production.
    
*   You can visually debug and inspect rendered output.
    
*   You write tests using Playwright’s powerful API, scoped to just the component.
