I've seen a few questions out there regarding this but I can't seem to make sense of any of the answers for my particular problem.

I have a mock object, lets call "object1", which I send to some method for testing, lets call testMethod(). So I end up calling 

testMethod(object1);

for testing. Now somewhere in this testMethod, there will be a part where it calls a method 

object1.toggleDisplay();

which is a void method. If the method were like 

object1.getDisplay()

where it actually returns something, I usually do

EasyMock.expect(object1.getDisplay()).andReturn(whatever);

However, this is a void method, and I would like to just test that this has been indeed been called for a certain amount of times. What is the easiest way to do this?

Thanks

If things haven't changed in the last few years, you use expectLastCall when setting up your expectations.

object1.toggleDisplay();
object.expectLastCall();

    Wait so I have to put object.expectLastCall() inside my actual method? I have my Unit test classes and my actual program classes separated, and would prefer not to have unit test code inside my actual program. – KWJ2104 Jul 30 '12 at 05:01
  • No, you put the method call and `expectLastCall().times(NUM_TIMES)` inside your unit test where you would have previously have used `EasyMock.expect(object1.getDisplay()).andReturn(whatever)` – DoctorRuss Jul 30 '12 at 08:37
  • Is there any way I can do this to target specific methods? Like for example I have methods toggleOn() and toggleOff() – KWJ2104 Jul 30 '12 at 17:17
  • Yes: just add `expectLastCall()` after each method expectation. It applies to the definition of the last (most recent) call :-) If in doubt, try it out! – DoctorRuss Jul 31 '12 at 08:18

object1.toggleDisplay();
EasyMock.expectLastCall().times(5);

or if you import statically the EasyMock methods:

import static org.easymock.EasyMock.*;

[...]

object1.toggleDisplay();
expectLastCall().times(5);
