// GET /blah
public Task<User> Get(string domainUserName)
{
        if (string.IsNullOrEmpty(domainUserName))

            throw new ArgumentException("No username specified.");

                    var user = userRepository.GetByUserName(domainUserName);

                    {
                        return user;
                    }

                    throw new HttpResponseException(Request.CreateErrorResponse(HttpStatusCode.NotFound, string.Format("{0} - username does not exist", domainUserName)));
                });
}

    var userController = new UserController(mockUserRepository.Object) { Request = new HttpRequestMessage() };
