Learn Mockito
Enhance your unit tests through practical mocking
Learn Mocking with Mockito
Unit testing is an essential practice in development that ensures the individual components of an application work as expected.
To test these components in isolation, we need to simulate or mock the external services they rely on.
Mockito stands out among mocking libraries for Java, due to huge popularity and adoption and its simple and intuitive API, while also having a very robust set of features.
In this course, we’ll start by exploring the basic concepts of mocks and stubs, how to create these using Mockito, and how to verify interactions in tests.
Then, we’ll look into more advanced techniques like working with spies, conditional stubbing, testing exceptions, BDD with Mockito and more.
Actual coding practice through a fully operational project is the best way to learn how to integrate Mockito in your Java unit tests
The essential guide for learning Mockito. The 3 modules cover the basic concepts and setup, and how to get started with defining mocks and verifying expected behavior.
Beyond the basics, you’ll also learn how to use stubbing, work with spies and partial mocks, test exceptions, use BDDMockito, and avoid common mistakes.
Everything you need to create robust unit tests with Mockito.
