JUnit 5 will be the next generation of JUnit. The goal is to provide a solid foundation for JVM-side testing. This includes Java 8 and higher, as well as allowing many styles of testing. We need your support as our users to keep the pace going. No matter how many donations we receive, we will continue to work on JUnit. Your support would allow us to focus more on JUnit and not just on weekends or in our spare moments. We want to meet regularly and have colocated work for a few days so that we can get more done in face-toface design and coding sessions. Your donations will make this a reality!

Mockito is a mocking tool that tastes great. It allows you to write beautiful tests using a simple API. Mockito won't leave you feeling hungover. The tests are easy to read and produce clear verification errors. Learn more about the features and motivations. The top 10 Java libraries across all libraries, and not just the testing tools. An analysis of 30.000 GitHub projects was done in late 2013. Mockito was ranked 9th in the main report. However, mockitocore and mockito all are the same tool so Mockito's actual position is number 4, just above Spring and Guava. This study is an indicator of the huge impact Mockito has on Java unit tests.

Many parts of a software program work together to accomplish their tasks. We trust our collaborators and don't care about real collaborators in unit testing. Mock objects can replace the unit under test's collaborators. We need to simulate the collaborators in order to test the unit in isolation. A mock object is a replacement for a collaborator and is used to test the unit. It simulates the object it replaces in an easy way. A Mock Object, unlike a stub does not verify that it is being used as expected. EasyMock was the first dynamic Mock Object generator. It has helped users to either generate code or relieve them from hand-writing mock Objects. EasyMock generates Mock Objects on the fly by using the Java proxy mechanism.
