Configure TestBed for Angular component testing by setting up the testing module with required providers and declarations, then creating mocks for dependencies to isolate component behavior during test execution.

Testing signals and computed values in Angular involves reading signal values directly in test assertions and verifying that computed signals update correctly when their dependencies change within the test execution flow.

Handle async Angular tests using fakeAsync to simulate asynchronous time passage and tick to flush pending microtasks, enabling deterministic testing of observables and promise-based code without actual delays.

You can use Vitest or Jest for Angular unit testing by configuring the test runner to integrate with TestBed, allowing you to execute component, service, and pipe tests across different testing frameworks.

Mock HTTP dependencies in Angular service tests by utilizing HTTP testing utilities to intercept requests, simulate server responses, and verify that your services send correct payloads and handle errors appropriately.

End-to-end testing with Playwright and Cypress is supported, providing guided patterns and integration templates to validate DOM interactions and complete user workflows across Angular applications.
