If you’ve been following the Angular ecosystem lately, you know that the "old way" of doing things is rapidly evolving. We’ve moved to Standalone Components, embraced Signals, and explored Zoneless applications. But for a long time, one piece of the puzzle felt stuck in the past: Testing.
For years, Karma and Jasmine were the industry standard. But let’s be honest—waiting for a browser to launch just to run a handful of unit tests felt increasingly sluggish in a world of instant feedback.
The wait is over. With the release of Angular 21, Vitest has officially become the default test runner for new projects. At Angular Academy, we don’t just follow the news; we lead the way. That’s why we are thrilled to announce that our Advanced Angular Testing Training has been completely updated for 2026 to put Vitest front and center.
Why the Switch to Vitest?
Vitest isn’t just a "faster Jasmine." It represents a fundamental shift in how we develop and verify our code:
Blazing Speed: Built on top of Vite, Vitest offers near-instant startup and incredible execution speed. No more "coffee breaks" while your test suite initializes.
Modern Ecosystem: It is TypeScript-first, supports ESM (ECMAScript Modules) natively, and integrates seamlessly with the modern Angular build pipeline.
Browser Mode: One of the biggest wins? Vitest can run in a real browser environment via Playwright or a DOM emulation library, giving you the best of both worlds: the speed of Node-based testing and the accuracy of a real DOM.
The New Standard: Since Karma was deprecated, the Angular team chose Vitest as the future. Learning it now isn't just an "extra skill"—it’s becoming a requirement for modern Angular development.
What’s New in our Testing Angular Course?
We didn’t just swap out a few labels. We’ve overhauled our curriculum to ensure you’re learning the cutting-edge patterns used in high-performance teams.
1. Mastering the Vitest API
Learn the nuances of Vitest, from setting up the environment to mastering its powerful mocking capabilities (vi.fn(), vi.spyOn). We also dive deep into async testing—which looks different in a Vitest/Zoneless world.
2. Testing Signals and Zoneless Components
Signals have changed how we manage state, and they require a new approach to testing. We’ll show you how to test reactivity, computed signals, and how to verify your logic without relying on zone.js.
3. Real-World Migration Strategies
Still stuck on Karma? We’ve got you covered. We include dedicated sections on migration paths, helping you move your legacy suites over to Vitest without losing your mind.
Hands-On, Live, and Expert-Led
At Angular Academy, we believe in "Learning by doing." This isn't a series of pre-recorded videos you'll never watch. It is a half-day, intensive, instructor-led workshop where we explore and try all the unit testing technics. You’ll be led by an industry expert with more than 11 years of experience with Angular projects.
Ready to Modernize Your Workflow?
The testing landscape has changed. Don't get left behind with deprecated tools and slow workflows. Join the next cohort of the Testing Angular Training and master the tools that will define the next decade of Angular development.
