What is TDD and how does Mockito fit into Java development?

TDD, or Test-Driven Development, is a software development process where tests are written before the code itself. Mockito is a popular mocking framework in Java that helps in creating mock objects for testing.

Can you explain how to use Mockito in a TDD approach?

Sure! In TDD, you first write a test case using Mockito to define the expected behavior of your code. Then, you implement the code to pass that test.

What are some common pitfalls when using Mockito?

Common pitfalls include not resetting mocks between tests, overusing mocks instead of real objects, and not verifying interactions properly.

Can you give an example of a simple test using Mockito?

Absolutely! Here's a simple example: you can mock a List and verify that a method adds an item to it. Use Mockito.when() to define behavior and Mockito.verify() to check interactions.
