yeah I think there is still a point of mocking you're not getting.
The TimerControl class is your mock, so it needs to be consumed by another
class.
You don't need to test if a mock calls itself.
Lets say you have a Controller:
public class MyController : Controller
{
private readonly ITimerControl _timer;
public MyController(ITimerControl timer)
{
_timer = timer;
}
void ButtonStart()
{
// some logic that might determine whether timer.TimerMethod() is called
}
}
// ignore the NUnit attributes, use microsoft's for your case
[TestFixture]
public class ControllerTests
{
// System under Test
private MyController _controllerSUT;
// Dependencies
private ITimerControl _timerControl;
[SetUp]
public void Setup()
{
_timerControl = MockRepository.GenerateMock<ITimerControl>();
_controllerSUT = new MyController(_timerControl);
}
[Test]
public void ButtonStart_should_call_timerControl_TimerMethod()
{
_controllerSUT.ButtonStart();
// you're asserting that ButtonStart when invoked should call the
dependency method
// this could be AssertWasNotCalled, depends on the logic you're
testing
_timerControl.AssertWasCalled(d => d.TimerMethod());
}
}
