Verify RaiseEvent

Jimmy hi,

given that your "Class Under Test" look somethign like:

    
public delegate void SampleEventDelegate(object sender, EventArgs e);
   
public class ClassUnderTest
{
     public event SampleEventDelegate SampleEvent;

     // A method that triggers the event:
     public void FireEvent()
     {
        SampleEvent(this,null);
     }
}

You can mock the "FireEvent" call like any call to other method:

[Test]
public void TestEvent()
{
  Mock mock = MockManager.Mock(typeof(ClassUnderTest));
  mock.ExpectCall("FireEvent");
            
  // Create an instance of the ClassUnderTest class.
  ClassUnderTest tested = new ClassUnderTest();
  // Specify the method that will be triggered by the SampleEvent event.
  tested.SampleEvent += delegate { System.Console.WriteLine("Hello, World!"); };
  // Trigger the event
  tested.FireEvent();

  MockManager.Verify();
}

I hope this is what you need. If not please let me know

The idea is to mock the actual handler method and verify that it has been called.
suppose you have:

Private Sub mText_UpdateTime(ByVal Countdown As Double) _
                             Handles mText.UpdateTime
    TextBox1.Text = Format(Countdown, "##0.0")
End Sub

where

mText = New TimerState

and

Class TimerState
    Public Event UpdateTime(ByVal Countdown As Double)
    Public Sub CallRaiseEvent()
        RaiseEvent UpdateTime(Duration - SoFar)
    End Sub
End Class

to check that RaiseEvent works we can mock mText_UpdateTime and Verify that it has been called.

<Test()> Public Sub TestRasieEvent()
      ' the handler class is now being mocked
      Dim handleMock As Mock = MockManager.Mock(Of HandlerEvents) 
      ' mock 1 call to mText_UpdateTime
      handleMock.ExpectCall("mText_UpdateTime")
      
      ' run test 
      Dim classUnderTest = New TimerState
      classUnderTest.CallRaiseEvent()
                   
       ' Verify that mText_UpdateTime was called (and mocked)
      MockManager.Verify()
End Sub

"Of HandlerEvents" ???
I couldn't find any classes with this name.

Its the name of the class that mText_UpdateTime is defined in.
you can write

MockManager.Mock(GetType(HandlerEvents)) 

Thanks a lot. Got it working.
