Writing Tests with Vitest: Hands-on Practice

In the previous chapter, we introduced Vitest and understood why it’s the new default. Now, let’s get our hands dirty and write some actual tests. You’ll find that writing tests with Vitest in Angular feels very familiar if you’ve used Jasmine/Jest before, as Vitest adopts a similar API.

We’ll start with a basic component test and then a service test.

Prerequisite: A new Angular v21 project (e.g., ng new vitest-demo --standalone) should already be configured with Vitest.
