Moq - verify that no methods were called

This is a unit-test from one of my controllers in an ASP.NET MVC project, using NUnit and Moq:

[Test]
public void Create_job_with_modelstate_errors_fails()
{
    var job = new JobDto();
    this.controller.ModelState.AddModelError("", "");

    ActionResult result = this.controller.Create(job);

    this.jobService.Verify(p => p.SaveJob(It.IsAny<JobDto>()), Times.Never());

    // some other asserts removed for brevity
}

This works fine, but from a maintenance point of view I think this line is more verbose than it needs to be:

this.postService.Verify(p => p.SavePost(It.IsAny<PostDto>()), Times.Never());

What i'd really like to be able to do is something equivalent to...

this.postService.VerifyNoMethodsCalled();

...as all i'm interested in is that my controller doesn't call any methods on the service. Is this possible using Moq?

You could create the Mock with MockBehavior.Strict, e.g.

this.postService = new Mock<IPostService>(MockBehavior.Strict);

That way, if you don't Setup any expectations, any calls to this.postService will fail

Modern answer (Moq 4.8 or later):

mock.VerifyNoOtherCalls();

That method makes sure no calls were made except for any previously verified ones. In this particular case, there are no mock.Verify(...) statements before it. Thus, it will make sure the mock was never called at all.

You will get a failure message like this if any calls were made:

This mock failed verification due to the following unverified invocations:
...

This does not require making the mock strict.
