testing - Service stack and Mocking, any tutorials?

Question

I am currently evaluating ServiceStack (to create rest based services in .Net). One of the areas of interest is the testing side. My rest service will have a number of app services injected in (currently using Autofac). What I need is a mechanism to test the rest layer and define expectations on my app layer (via MOQ), so I am not doing integration tests but unit testing this layer?

Any ideas on how to do this?

A ServiceStack Service is just like any normal C# Service class and can be mocked in exactly the same way like any other class. The minimum dependency for a ServiceStack Service is implementing the dependency-free IService interface marker and where any service just accepts a Request DTO and returns any object.

One way to Unit test ServiceStack services is to use the DirectServiceClient as seen in this example, a benefit of this is that it lets you use the same Unit Test as an integration test - testing all the different XML, JSON, JSV and SOAP endpoints.

Otherwise you can unit test and Mock it like any other class, e.g:

var service = new TestService {
   MyDependency = new Mock<IMyDependency>().Object
};
var response = service.Get(new Test { Id = 1 });
Assert.That(response.Result, Is.EqualTo("Hello, 1"));
