Stubs: Simple Event Usage

public interface IExample {
   event EventHandler SimpleEvent;
}

You can use +=, -=, and Invoke on event handlers to handle most simple scenarios.

public void SimpleEventUsage() {
   var stub = new StubExample();
   IExample example = stub;

   // you can add and remove handlers like normal
   int count = 0;
   stub.SimpleEvent += (sender, e) => count++;

   // you can invoke the event like you would from within the stub
   stub.SimpleEvent.Invoke(stub, EventArgs.Empty);
   Assert.Equal(1, count);

   // you can access all the handlers that have been added.
   Assert.Single(stub.SimpleEvent.handlers);
}
