How to verify that method was NOT called in Moq?


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 used:

mock.Verify(foo => foo.Execute("ping"), Times.Never());

Accepted Answer

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<IMoq>(MockBehavior.Strict)

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

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

Run a verify after the test which has a Times.Never enum set. e.g.

_mock.Verify(service => service.ShouldntBeCalled(),Times.Never());
