How can I use Jasmine for advanced mocking in my tests?

You can use Jasmine's built-in spies to create mocks for functions. This allows you to track calls and return values.

Can you show me an example of creating a spy for a function?

Sure! You can create a spy like this: const mySpy = jasmine.createSpy('myFunction'); Then you can call it and check if it was called.

What if I want to mock a method of an object?

You can use spyOn(object, 'methodName') to mock a method of an object. This will replace the method with a spy.

How do I check if the spy was called with specific arguments?

You can use expect(mySpy).toHaveBeenCalledWith(arg1, arg2); to verify that the spy was called with the expected arguments.
