Daniel Cazzulino just announced the birth of Moq, now this is mocking done right.
// ShouldExpectCallWithArgument
var mock = new Mock<IFoo>();
mock.Expect(x => x.DoInt(1)).Returns(11);
mock.Expect(x => x.DoInt(2)).Returns(22);
Assert.AreEqual(11, mock.Instance.DoInt(1));
Assert.AreEqual(22, mock.Instance.DoInt(2));
Lambda is starting to make my mouth water.
