As you can see, by utilizing the jest.fn () method to create a mock function and then defining its implementation using the mockImplementation method, we can control what the function does and spy on it to see how many times it was called.
The first step is to call jest.spyOn(component, 'bar'). This will replace the method with a mock version. By default the mock version will behave like the original method. Spying on a method has other benefits (like being able to assert the number of times a method is called), but those won't be discussed in this article.
