What are the best practices for mocking in Spring?

When mocking in Spring, it's essential to use frameworks like Mockito. Focus on mocking dependencies rather than the class under test.

Can you explain why it's important to mock dependencies?

Mocking dependencies allows you to isolate the unit of work, ensuring that tests are focused and not affected by external factors.

What are some common mistakes to avoid when mocking?

Common mistakes include over-mocking, which can lead to brittle tests, and not verifying interactions, which can miss important behaviors.

How do I set up Mockito in a Spring project?

To set up Mockito, include the dependency in your pom.xml or build.gradle, and use the @Mock annotation in your test classes.
