[Nmock-general] EventAdd part 2

[Michael W. <mic...@gm...>]

I figure out my question regarding EventAdd. There were at least two
potential solutions to the code I posted before. I thought I'd post it
for others who might have trouble. The simplest was to create a
DummyMatcher that always returned true.  Here is the code for that:

    public interface I
    {
        event EventHandler MyEvent;
    }

    public class C : I
    {
        public event System.EventHandler MyEvent;
    }

    public class Consumer
    {
        public void DoStuff(I i)
        {
            i.MyEvent += new EventHandler(i_MyEvent);
        }

        public void i_MyEvent(object sender, EventArgs a)
        {
        }
    }

    [TestFixture]
    public class TestClass
    {
        [Test]
        public void TestOne()
        {
            Mockery m = new Mockery();
            I i = (I) m.NewMock(typeof(I));

            Consumer c = new Consumer();


            Expect.Once.On(i).EventAdd("MyEvent", new MyMatcher());

            c.DoStuff(i);

            m.VerifyAllExpectationsHaveBeenMet();

        }

        public void evhandler(object sender, EventArgs a)
        {
        }
    }

    public class MyMatcher : Matcher
    {
        public override bool Matches(object o)
        {
            return true;
        }

        public override void DescribeTo(System.IO.TextWriter writer)
        {

        }


    }

The other solution was to pass in an EventHandler that wrapped the
exact same method that would be used in the code. That looked like:


            Expect.Once.On(i).EventAdd("MyEvent", new
EventHandler(c.i_MyEvent));

For my purposes the first was sufficient. The second wouldn't work if
the method was not public. I guess you'd have to use reflection.
