Use Mockito to verify that nothing is called after a method

Question

I'm using Mockito to write a unit test in Java, and I'd like to verify that a certain method is the last one called on an object.

I'm doing something like this in the code under test:

row.setSomething(value); row.setSomethingElse(anotherValue); row.editABunchMoreStuff(); row.saveToDatabase(); 

In my mock, I don't care about the order in which I edit everything on the row, but it's very important that I not try to do anything more to it after I've saved it. Is there a good way to do this?

Note that I'm not looking for verifyNoMoreInteractions: it doesn't confirm that saveToDatabase is the last thing called, and it also fails if I call anything on the row that I don't explicitly verify. I'd like to be able to say something like:

verify(row).setSomething(value); verify(row).setSomethingElse(anotherValue); verifyTheLastThingCalledOn(row).saveToDatabase(); 

If it helps, I'm switching to Mockito from a JMock test that did this:

row.expects(once()).method("saveToDatabase").id("save"); row.expects(never()).method(ANYTHING).after("save"); 

Answer 1

I think it requires more custom work.

verify(row, new LastCall()).saveToDatabase(); 

and then

public class LastCall implements VerificationMode {     public void verify(VerificationData data) {         List<Invocation> invocations = data.getAllInvocations();         InvocationMatcher matcher = data.getWanted();         Invocation invocation = invocations.get(invocations.size() - 1);         if (!matcher.matches(invocation)) throw new MockitoException("...");     } } 

Previous Answer:

You are right. verifyNoMoreInteractions is what you need.

verify(row).setSomething(value); verify(row).setSomethingElse(anotherValue); verify(row).editABunchMoreStuff(); verify(row).saveToDatabase(); verifyNoMoreInteractions(row);
