Unintended Call Count mutation for recursive mocks

[Isaac Abraham]

I have a recursive mock. I'm doing an arrangement on the child mock, but this has an unintended side effect in that the call count of the parent mock is incremented - this should not be happening.

public interface IMyInterface
{
   IOther GetOther();
}
public interface IOther
{
   int Foo(string test);
}

[Fact]
public void TestMethod()
{
   var myInterface = Mock.Create<IMyInterface>();

   Mock.Assert(() => myInterface.GetOther(), Occurs.Never());
   Mock.Arrange(() => myInterface.GetOther().Foo(null)).IgnoreArguments().Returns(1);
   Mock.Assert(() => myInterface.GetOther(), Occurs.Never()); // BANG
}

Hi Isaac Abraham,

Thank you for reporting this. We managed to reproduce the unwanted behavior thanks to your sample and indeed it seems like a bug in JustMock. It is now into our backlog in order to be fixed soon.

As a token of gratitude, I have granted you some Telerik points.
