Is there a way of having something like jUnit Assert message argument in Mockito's verify method?

Question

Let's assume a snippet of testing code:

Observable model = Class.forName(fullyQualifiedMethodName).newInstance(); Observer view = Mockito.mock(Observer.class); model.addObserver(view); for (Method method : Class.forName(fullyQualifiedMethodName).getDeclaredMethods()) {   method.invoke(model, composeParams(method));   model.notifyObservers();   Mockito.verify(     view, Mockito.atLeastOnce()   ).update(Mockito.<Observable>any(), Mockito.<Object>any()); } 

Mockito.verify method throws an exception if a method in a model hasn't invoked Observable.setChanged() method.

Problem: without adding loggers/System.print.out I can't realize what's the current method that has failed the test. Is there a way of having something similar to jUnit Assert methods:

Assert.assertEquals(   String.format("instances %s, %s should be equal", inst1, inst2),   inst1.getParam(),    inst2.getParam() );

SOLUTION:

verify(observer, new VerificationMode() {   @Override   public void verify(VerificationData data)   {     assertTrue(         format(             "method %s doesn't call Observable#setChanged() after changing the state of the model",             method.toString()         ),         data.getAllInvocations().size() > 0);   } }).update(Mockito.<Observable>any(), Mockito.<Object>any()); 

Answer 1

This question is ancient, but Mockito v2.1.0+ now has a built-in feature for this.

verify(mock, description("This will print on failure")).someMethod("some arg"); 

More examples included from @Lambart's comment below:

verify(mock, times(10).description("This will print if the method isn't called 10 times")).someMethod("some arg"); verify(mock, never().description("This will print if someMethod is ever called")).someMethod("some arg"); verify(mock, atLeastOnce().description("This will print if someMethod is never called with any argument")).someMethod(anyString()); 

Answer 2

This does the trick (simple and clear):

try {  verify(myMockedObject, times(1)).doSomthing(); } catch (MockitoAssertionError error) {     throw new MockitoAssertionError("Was expecting a call to myMockedObject.doSomthing but got ", error); }
