Mockito Crib Sheet #2

5. Capturing arguments passed to a mock:

       String expected = "test string";
   
      toTest.hitTakeArgumentReturnVoid(expected);
   
      ArgumentCaptor stringCaptor = ArgumentCaptor.forClass(String.class);
      Mockito.verify(mock).takeArgumentReturnVoid(stringCaptor.capture());
      Assert.assertEquals(expected, stringCaptor.getValue());

Note that this capture code can come after the call to the production method.

6. Verifying that a method is never called:

       Mockito.verify(mock, Mockito.never()).takeArguments(Mockito.anyString(), Mockito.anyInt());

Or, equivalently:

      
       Mockito.verify(mock, Mockito.times(0)).takeArguments(Mockito.anyString(), Mockito.anyInt());

But I don't like this as the set of methods never called is infinite.
