How to verify that method was NOT called in Moq?

Question

How do I verify that method was NOT called in Moq?

Does it have something like AssertWasNotCalled?

UPDATE: Starting from Version 3.0, a new syntax can be us

Answer 1

UPDATE: Since version 3, check the update to the question above or Dann's answer below.

Either, make your mock strict so it will fail if you call a method for which you don't have an expect

new Mock(MockBehavior.Strict)

Or, if you want your mock to be loose, use the .Throws( Exception )

var m = new Mock(MockBehavior.Loose);
m.Expect(a => a.moo()).Throws(new Exception("Shouldn't be called."));
