Recursive Mocks

[Richard Banks]

In Rhino I can do this:

		[Fact]
		public void Rhino_RecursiveMocks()

		{
			var monkey = MockRepository.GenerateMock<IMonkey>();
			monkey.Expect(m => m.Name).PropertyBehavior();

			monkey.Name = "Spike";
			monkey.Expect(m => m.Keeper().AssignedMonkey).Return(monkey);
			Assert.NotNull(monkey.Keeper());

			Assert.Equal("Spike", monkey.Keeper().AssignedMonkey.Name);
		}

But the following in NSub doesn't work

		[Fact]
		public void NSubstitute_RecursiveMocks()

		{
			var monkey = Substitute.For<IMonkey>();
			monkey.Keeper().AssignedMonkey.Returns(monkey);

			monkey.Name = "Spike";
			Assert.NotNull(monkey.Keeper());
			Assert.Equal("Spike",monkey.Keeper().AssignedMonkey.Name);

		}

Relevant code for mocks is:

	public interface IMonkey

	{
		string Name { get; set; }
		IZooKeeper Keeper();
	}

	public interface IZooKeeper
	{
		IMonkey AssignedMonkey { get; set; }

	}

Hi Richard,

Recursive mocks aren't implemented yet, but are planned for the 1.0 release.

Another 1.0 feature currently missing is ordered mocks.

Regards,

David

I would've said a future feature, rather than commiting myself to a specific release.

That way we could come up with new versions with extra features. ;)

It's on the internet now, and the internet never forgets!! :-)

I'm sure we won't hold you to it.

Cue a Google-style perpetual beta! :P

This is what I get for not letting the product owner do the talking. I'm so fired. ;)

Hi Richard,

I've just checked in a first attempt at recursive mocking for members that return interfaces.

Some examples here: http://bit.ly/bVddbO

It would be awesome if you could do a build from the repo, try it out on your example and see if it works the way you want it to. (Otherwise I'll give it a go once you post the code from your DDDSydney session.)

Cheers,

David

Will do.

[Richard Banks]

And done.

And working (using that code I showed demoed Saturday)

Nice stuff :-)
