Answer 1

As of this commit Moq now supports the mocking of delegates, for your situation you would do it like so:

var fooMock = new Mock();
var a = new A(fooMock.Object);

Then you can verify the delegate was invoked:

fooMock.Verify(f => f(5), Times.Once);

Or:

fooMock.Verify(f => f(It.IsAny()), Times.Once);
