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.
