To write unit tests for Angular signal components with OnPush, use TestBed to configure the testing module and component harnesses to interact with the UI. This approach supports modern testing patterns for both Vitest and Jasmine test runners in Angular v21+ applications.

Yes, you can use Vitest instead of Jasmine for Angular testing workflows. The testing setup supports both frameworks, allowing you to configure test infrastructure, mock dependencies, and execute integration tests for signal-based components and HTTP interactions.

The best way to test services using inject() and HTTP interactions is through TestBed configuration and mock dependencies. This setup validates service logic and HTTP requests in unit and integration testing scenarios using either Vitest or Jasmine.

You set up test infrastructure for Angular v21+ applications by configuring Vitest or Jasmine, defining TestBed modules, and creating reusable test utilities. This foundation enables consistent mocking and testing of components, signals, and HTTP interactions.

Yes, Angular TestBed works seamlessly with component harnesses for testing signal-based components. This combination allows you to simulate user interactions, verify OnPush change detection behavior, and validate component state in unit and integration tests.

You need to mock dependencies when testing Angular components with signals to isolate component logic and prevent side effects from inject() services or HTTP interactions. This ensures reliable and predictable Vitest or Jasmine test execution.
