org.mockito.exceptions.misusing.MissingMethodInvocationException: when() requires an argument which has to be 'a method call on a mock'. For example: when(mock.getArticles()).thenReturn(articles); Also, this error might show up because: 1. you stub either of: final/private/equals()/hashCode() methods. Those methods *cannot* be stubbed/verified. 2. inside when() you don't call method on mock but on some other object. 3. the parent of the mocked class is not public. It is a limitation of the mock engine.
