I have a simple event which does not derive from event args. It seems that there is no way to raise these events on mocked objects: -

public interface IFoo

{

event EventHandler<string> Message;

}

[Fact]

public void Sample()

{

bool fired = false;

var create = Mock.Create<IFoo>();

create.Message += (o,e) => fired = true;

Mock.Raise(() => create.Message += null, "Test"); //bang

Assert.True(fired);

}

It appears that either (a) you must create a custom delegate rather than using EventHandler<T>, or (b) create a full class that inherits from EventArgs. If so - this is slightly cumbersome to use. It would be much better if there were no restriction that the type of T on EventHandler must derive from EventArgs.
