Asserting that a method is called exactly one time

Question

I want to assert that a method is called exactly one time. I\'m using RhinoMocks 3.5.

Here\'s what I thought would work:

Answer 1

I have been using the AssertWasCalled extension to get around this problem. This is the best I could find/come up with but it would be better if I didn't have to specify the call twice.

    [Test]
    public void just_once()
    {
        var key = "id_of_something";

        var source = MockRepository.GenerateStub();

        // set a positive expectation
        source.Expect(x => x.GetSomethingThatTakesALotOfResources(key))
            .Return(new Something())
            .Repeat.Once();

        var client = new Client(soure);
        client.GetMeMyThing(key);
        client.GetMeMyThing(key);

        source.AssertWasCalled(x => x.GetSomethingThatTakesALotOfResources(key),
                               x => x.Repeat.Once());
        source.VerifyAllExpectations();
    }
