How can I mock dependencies in unit tests?
You can use libraries like Mockito or Jest to create mock objects for your dependencies.
Can you give me an example using Mockito?
Sure! You can use @Mock
annotation to create a mock object and then use when(...).thenReturn(...)
to define its behavior.
What if I want to verify interactions with the mock?
You can use verify(mockObject).methodCall()
to check if a specific method was called on the mock.
Are there any best practices for mocking?
Yes, keep your mocks simple, avoid over-mocking, and ensure your tests remain readable.
