What are the benefits of using mockito in tests?

Mockito allows you to create and configure mock objects. Using Mockito greatly simplifies the development of tests for classes with external dependencies. If you use Mockito in tests you typically: Mock away external dependencies and insert the mocks into the code under test Execute the code under test Validate that the code executed correctly 3.
Keeping this in consideration, what kind of tests can you do with Mockito?
Mockito keeps track of all the method calls and their parameters to the mock object. You can use the verify() method on the mock object to verify that the specified conditions are met. For example, you can verify that a method has been called with certain parameters. This kind of testing is sometimes called behavior testing.
Furthermore, what's the purpose of using the Mockito framework? The main purpose of using the Mockito framework is to simplify the development of a test by mocking external dependencies and use them in the test code. As a result, it provides a simpler test code that is easier to read, understand, and modify. We can also use Mockito with other testing frameworks like JUnit and TestNG.
