What are some advanced mocking techniques in Angular?

Advanced mocking techniques in Angular include using libraries like Jasmine and Sinon, creating custom spies, and utilizing TestBed for dependency injection.

Can you explain how to use TestBed for mocking services?

Sure! TestBed allows you to configure a testing module where you can provide mock services. You can use 'providers' to replace real services with mocks.

What is the difference between a spy and a stub?

A spy records the calls made to a function, while a stub provides predefined responses to function calls without recording them.

How do I mock HTTP requests in my tests?

You can use HttpClientTestingModule to mock HTTP requests. It allows you to simulate responses and test your components without making real HTTP calls.

Are there any best practices for mocking in Angular?

Yes, some best practices include keeping mocks simple, avoiding over-mocking, and ensuring that your tests remain readable and maintainable.
