Why is my test failing?

[matthiasguentert]

Consider the following assemblies, where each of them are having a marker interface:

• Api (IApiMarker)
• Infrastructure (IInfrastructureMarker)
• Application (IApplicationMarker)
• Domain (IDomainMarker)
• SharedKernel (ISharedKernelMarker)

... and further the following references:

1. Api has a reference to Infrastructure
2. Infrastructure has a reference to Application
3. Application has a reference to Domain and SharedKernel
4. Domain has a reference to SharedKernel
5. SharedKernel doesn't have any references

Now, I'd like to make sure, that these references stay in place and that dependencies only flow inwards (clean architecture).

I therefore created a test, let's call it ArchTest which references Api.

Now I'd like to ensure, that domain holds a reference to sharedkernel... (not sure if this test makes much sense...) But, why is the following test failing even so Domain has a reference to SharedKernel?

[Fact]
public void Domain_should_have_reference_to_shared_kernel()
{
    var domain = typeof(IDomainMarker).Assembly;
    var sharedKernel = typeof(ISharedKernelMarker).Assembly;

    var result = Types.InAssembly(domain)
        .Should()
        .HaveDependencyOn(sharedKernel.GetName().Name)
        .GetResult();
    
    result.IsSuccessful.ShouldBeTrue();
}

P.S: Using NetArchTest.Rules v1.3.2
