Adding assertions for logging behaviour to my unit tests have been a long standing item om my ToDo list. It is a Mockito's wrapper that provides same API plus static method mocking and other features. This is also the recommended way of matching arguments because it makes tests clean & simple. Mockito will not be able to figure out which argument type to match against the any() matcher.

Mockito is an open source testing framework for Java released under the MIT License. If you use a matcher for one argument of a call, you need to use it for all the arguments, so the Matchers class (as well as its subclass Mockito) contains a bunch of standard matchers like eq() and anyObject() for simple cases, and argThat() which allows you to use a more complex custom matcher. In this article well discuss the basic annotations in the Mockito library - @Mock, @Spy, @Captor, and @InjectMocks. This dependency is simple enough and does not bring any additional or redundant libraries. Custom argument matchers use hamcrest matchers, so you can use your existing hamcrest matchers.
