Moq'ing the raising of events multiple times
c#, moq, unit-testing
Solution
`mockFoo.Raise` should be fine, raising the event three times... Can you put a breakpoint in the event handler and check how many times is it called?
Another potential mistake here as I can see, is that you should first tell Moq to start tracking all sets/gets of a property before you can verify it (and before you raise the events):
// start "tracking" sets/gets to this property
mockFoo.SetupProperty(foo=> foo.Orientation);
Problem
In a particular unit test I'm trying to raise an event multiple times and then to veryify a property value after the final event has been raised. I have something like ``` public void TurnRight() { var mockFoo = new Mock<IFoo>(); SomeService someService= new SomeService (); someService.Foo= mockFoo.Object; mockFoo.Raise(foo=> foo.TurnedRight += null, EventArgs.Empty); mockFoo.Raise(foo=> foo.TurnedRight += null, EventArgs.Empty); mockFoo.Raise(foo=> foo.TurnedRight += null, EventArgs.Empty); mockFoo.VerifySet(foo=> foo.Orientation = Orientation.West); } ``` Orientation actually only changed to east (as I believe the event is only getting raised once). Am I doing something wrong? This is the first time i've used moq so I'm probably missing something. Cheers J edit... the correct code i should have been using ``` public void TurnRight() { var mockFoo = new Mock<IFoo>(); SomeService someService= new SomeService (); someService.Foo= mockFoo.Object; mockFoo.SetupProperty(foo=> foo.Orientation); mockFoo.Raise(foo=> foo.TurnedRight += null, EventArgs.Empty); mockFoo.Raise(foo=> foo.TurnedRight += null, EventArgs.Empty); mockFoo.Raise(foo=> foo.TurnedRight += null, EventArgs.Empty); Assert.AreEqual(mockFoo.Object.Orientation, Orientation.South); } ```
