Start host for integration test from test base throws not implemented exeption

public class IntegrationTestBase : IDisposable
{
    protected readonly ServiceStackHost appHost;

    public const string BaseUri = "http://localhost:5000/";

    public IntegrationTestBase()
    {
        Licensing.RegisterLicense(
            "license key");
        appHost = new BasicAppHost(typeof(AppHost).GetAssembly())
            {
                ConfigureContainer = container =>
                {
                    //Add your IoC dependencies here
                }
            }
            .Init()
            .Start(BaseUri);
    }

    public void Dispose()
    {
        appHost.Dispose();
    }
}

I need to write integration tests and used this code to start a host in order to make tests but it throws not implemented exception.
