What are some tips for integration testing with Mockito?

When using Mockito for integration testing, consider the following tips: 1. Use @Mock and @InjectMocks annotations for cleaner code. 2. Keep your tests isolated by mocking dependencies. 3. Use ArgumentCaptor to verify interactions. 4. Ensure proper setup and teardown of your test environment.

Can you explain how to use @Mock and @InjectMocks?

Sure! The @Mock annotation creates a mock instance of a class, while @InjectMocks initializes the class and injects the mocks into it. This helps in testing the class in isolation.

What is ArgumentCaptor and how do I use it?

ArgumentCaptor is a feature in Mockito that allows you to capture arguments passed to mocked methods. You can use it to verify that the correct values are being passed during interactions.

Are there any best practices for writing these tests?

Yes, some best practices include: keeping tests small and focused, naming tests clearly, avoiding complex logic in tests, and ensuring that tests are repeatable and independent.
