Junit and Mockito are both popular testing frameworks used for Java applications. While Junit is used for unit testing, Mockito is used for creating mock objects to test the interactions between different parts of the code. In this blog post, we’ll compare Junit and Mockito and help you choose the right framework for your testing needs.
Junit
JUnit is a testing framework for Java that is used for unit testing. Some of the key features of JUnit include:
- Simple and easy to use: JUnit is easy to set up and use, making it a popular choice for developers.
- Test-driven development: JUnit promotes test-driven development by providing a framework for writing and executing tests as you develop your code.
- Test suites: JUnit allows you to group tests into test suites, making it easier to manage and run tests.
- Assertions: JUnit provides a range of assertions that allow you to test your code for expected results.
Mockito
Mockito is a mocking framework for Java that allows you to create mock objects for testing purposes. Some of the key features of Mockito include:
- Easy mock creation: Mockito allows you to easily create mock objects, making it easier to test interactions between different parts of your code.
- Verification: Mockito provides a way to verify the interactions between mock objects and the code being tested.
- Stubbing: Mockito allows you to stub methods of mock objects to return specific values or throw exceptions.

Comparison Table
To help you compare JUnit and Mockito, we’ve put together a table outlining the key features of each framework:
| Feature | JUnit | Mockito |
| Testing type | Unit testing | N/A |
| Ease of use | Simple and easy to use | Easy mock creation |
| Test-driven development | Promotes test-driven development | N/A |
| Test suites | Allows grouping tests into test suites | N/A |
| Assertions | Provides a range of assertions for testing | N/A |
| Mock creation | N/A | Easy mock creation |
| Verification | N/A | Provides a way to verify the interactions between mock objects and the code being tested |
| Stubbing | N/A | Allows you to stub methods of mock objects to return specific values or throw exceptions |
In conclusion, JUnit and Mockito are both powerful testing frameworks used for Java applications. JUnit is primarily used for unit testing, while Mockito is used for creating mock objects to test interactions between different parts of the code. Ultimately, the choice between JUnit and Mockito depends on your specific testing needs. If you need to create mock objects for testing, then Mockito is the better option. If you only need to perform unit testing, then JUnit is the best choice.
