What are the differences between Mockito and PowerMock?

What are the differences between Mockito and PowerMock?

Mockito is a popular mocking framework for unit tests in Java, while PowerMock extends Mockito to mock static methods and constructors.

When should I use PowerMock instead of Mockito?

Use PowerMock when you need to mock static methods, final classes, or private methods, which Mockito cannot handle.

Are there any performance concerns with using PowerMock?

Yes, PowerMock can introduce performance overhead due to its bytecode manipulation, so use it judiciously.

Can I use both Mockito and PowerMock together?

Yes, you can use them together. PowerMock can be configured to use Mockito for mocking non-static methods.

What are some best practices for using Mockito?

Some best practices include keeping tests isolated, using meaningful names for mocks, and verifying interactions.
