如何在Moq中模拟没有参数的熔炉并填充 [英] How to mock a melthod with out paramter in Moq AND fill the out

问题描述

我在Stackoverflow中看到了有关最小起订量参数的几个问题，我的问题是如何填充此参数:让我们编写代码:

I have see several questions here in Stackoverflow about out parameters in MOQ, my question is how fill this parameter: Lets to code:

[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());
}

我要测试这篇文章:

[Test]
public void Should_Status_Be_Create_With_Valid_XML()
{
    // 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);
    }
}

问题

发送方法(POST)中的

我的response对象用于后响应，但是_messageService.Process负责填充response对象. 在测试方法Should_Status_Be_Create_With_Valid_XML中，我模拟了_messageService.Process并且response对象未填充Request.CreateResponse(HttpStatusCode.Created, response.ToString());

Problem

My response object in Send method (POST) is used in post response but the _messageService.Process is responsible to fill the response object. In test method Should_Status_Be_Create_With_Valid_XML I mock _messageService.Process and response object is not fill ocorr error Null reference in Request.CreateResponse(HttpStatusCode.Created, response.ToString());

response为空！

推荐答案

当然response为null，任何地方都没有代码可以将其设置为任何值(在您的服务方法或模拟中).

Of course response is null, there's no code anywhere that would set it to anything (in your service method or your mock).

由于您正在嘲笑通常会填充它的方法，因此由您来指定设置方式.在调用Setup之前，应使用期望作为调用该方法时的值来填充对象.

Since you're mocking the method that would usually fill it in, it's up to you to specify how it is set. You should fill in the object before calling Setup with what you expect to be the value when that method is called.
