Setting up testing for ServiceStack 3.9... project. I was having trouble figuring out how to create my test with service stack. After looking at the endpoint tests from the service stack examples I decided to organize my tests using the following layout.

ServiceTest.cs

using NUnit.Framework;
using ServiceStack.ServiceClient.Web;
using example_proj.Services;

namespace Tests
{
    [TestFixture]
    public class ServiceTests
    {
        private TestAppHost _appHost;

        public JsonServiceClient CreateClient()
        {
            return new JsonServiceClient(Config.AbsoluteBaseUri);
        }

        [TestFixtureSetUp]
        public void TestSetup()
        {
            _appHost = new TestAppHost();
            _appHost.Init();
            _appHost.Start(Config.AbsoluteBaseUri);
        }

        [TestFixtureTearDown]
        public void TestTearDown()
        {
            _appHost.Stop();
            _appHost.Dispose();
        }

        [Test]
        public void TestGetAllThings()
        {
            var client = CreateClient();
            var response = client.Get<ThingsResponse>("things");
            Assert.IsTrue(response.Things.Count > 0);
        }


        [Test]
        [ExpectedException("ServiceStack.ServiceClient.Web.WebServiceException")]
        public void TestThingDoesNotExist()
        {
            var client = CreateClient();
            var response = client.Get<ThingsResponse>("thing/nope");
            Assert.IsTrue(response.ResponseStatus.ErrorCode == "thing not found");
        }
    }
}

TestAppHostBase.cs

using ServiceStack.OrmLite;
using ServiceStack.OrmLite.SqlServer;
using ServiceStack.WebHost.Endpoints;
using example_proj.Services;

namespace Tests
{

    public class TestAppHost : AppHostHttpListenerBase  
    {
        public TestAppHost() : base("testing http listener", typeof(ExampleService).Assembly) {}

        public override void Configure(Funq.Container container)
        {
  	    const string connectionString = @"Data Source=.\SQLEXPRESS;Initial Catalog=test-db;Integrated Security=SSPI";
            container.Register<IDbConnectionFactory>(c =>
                                                     new OrmLiteConnectionFactory(connectionString,
                                                                                  SqlServerOrmLiteDialectProvider.
                                                                                      Instance));
        }
    }
}

Just noticed the spacing for the directory structure didn't come through; here it is again:

/Solution
/Example_proj
/Example_proj/Global.asax.cs - containing app init and AppHost
/Example_proj/ServiceModels

/Tests
/Tests/TestAppHostBase.cs (based on self hosted AppHostListenerBase)
/Tests/ServiceTest.cs
