[HttpPost]
public HttpResponseMessage Send(SmsMoRequest sms)
{
    if (sms == null)
        return Request.CreateResponse(HttpStatusCode.BadRequest);

    SmsMoResponse response;
    _messageService.Process(sms, out response);
    return Request.CreateResponse(HttpStatusCode.Created, response.ToString());
}

    // Arrange
    var messageServiceMoq = new Mock<IMessageService>();
    SmsMoResponse response;
    messageServiceMoq.Setup(mock => mock.Process(It.IsNotNull<SmsMoRequest>(), out response));
    _kernel.Bind<IMessageService>().ToConstant(messageServiceMoq.Object);
    var client = new HttpClient(_httpServer) { BaseAddress = new Uri(Url) };

    // Act
    using (var response = client.PostAsync(string.Format("Api/Messages/Send"), ValidContent()).Result)
    {
        // Asserts
        response.IsSuccessStatusCode.Should().BeTrue();
        response.StatusCode.Should().Be(HttpStatusCode.Created);
    }
