BDD Question: Low Level Behavior And Wrapper Methods?

I have a service object with an interface explicitly defined for it. I like this because it let’s me unit test the things that need the service without having to worry about the implementation detail of the actual service.

public interface IMyService

{

  public void DoSomething();

  public void AnotherThingHere();

}

When I get to the implementation of this service and I start specifying the behavior through my specification/tests, I create a class that has a dependency on another interface – ISomeRepository. This repository is used in both methods of the actual service implementation.

For the “AnotherThingHere” method, I end up with several specification/tests because that method has some good business logic in it.

For the “DoSomething” method, though, the real implementation is only a pass-through to the repository and my specification/test ends up looking like this:

[TestFixture]

public class When_doing_something: ContextSpecification

{

 ISomeRepository repo;

 public override void Context()

 {

   repo = MockRepository.GenerateMock<ISomeRepository>();

   IMyService myService = new MyService(repo);

   myService.DoSomething();

 }

 [Test]

 public void Should_do_something()

 {

   repo.AssertWasCalled(r => r.DoSomething());

 }

}

I know this specification is necessary because I am using the “DoSomething” method of IMyService in other parts of the system. I think there is value in having an IMyService interface explicitly because it simplified the specification/tests for the parts of the system that need to use it, and decoupled the system to a point that made it much easier to code and change.

So my question is, do you see any real value in a specification/test name like “When doing something, should do something”? or should I be looking at this test from a different “style” or perspective?

I think this specification/test is valuable, but I also think the test name and observation name are silly since they say the same thing. Advice? Different naming suggestions? What am I missing or just not seeing? or is this ok and I’m just running on 25% brain power due to lack of sleep today?
