About invoking event, need your suggestions

Hi,

The example below should answer both questions:

The Code Under Test:

public class Foo
{

    public void AddHttpListener(HTTPListener httpListener)
    {    
        httpListener.RequestReceived += OnRequestReceived;
    }

    public void OnRequestReceived(object sender, EventArgs e)
    {
        //some logic
    }
}

public class HTTPListener
{
    public event EventHandler RequestReceived;
}

And the test code:

[TestMethod , Isolated]
public void TestMethod1()
{

    //ARRANGE
    var foo = Isolate.Fake.Instance<Foo>(Members.CallOriginal);
    var httpListener = new HTTPListener();

    //ACT
    foo.AddHttpListener(httpListener);
    Isolate.Invoke.Event(() => httpListener.RequestReceived += null, null, EventArgs.Empty);

    //ASSERT
    Isolate.Verify.WasCalledWithAnyArguments(() => foo.OnRequestReceived(null, null));
}

You can tell that the eventhandler is correctly assigned because the invokation of the event triggered it (Isolate.Verify) shows that.

2 things to know about the test above:
1) The test should be [Isolated] so the invokation would work.
2) You can use verify only on fake objects, thats why I faked Foo with call original.

Please let me know if it helps.
