如何使用Moq使用JSON主体创建模拟HTTP post请求

Question

我正在尝试基本上做标题所说的为了对我的api控制器进行单元测试,但我找不到合适的方法并且无法承担花费太多时间.这是我的代码.

[TestMethod]
public void Should_return_a_valid_json_result()
{
    // Arrange
    Search search = new Search();
    search.Area = "test";
    string json = JsonConvert.SerializeObject(search);

    var context = new Mock<HttpContextBase>();
    var request = new Mock<HttpRequestBase>();

    request.Setup(r => r.HttpMethod).Returns("POST");
    request.Setup(r => r.InputStream.ToString()).Returns(json);

    context.Setup(c => c.Request).Returns(request.Object);

    var controller = new UserController();
    controller.ControllerContext = new HttpControllerContext() {  RequestContext = context };

   //more code

}

最后一行返回错误CS0029无法将类型'Moq.Mock System.Web.HttpContextBase'隐式转换为'System.Web.Http.Controllers.HttpRequestContext'.

我也不确定我应该使用的Moq语法,其他问题,示例和Moq文档对我没什么帮助.

如果只是为了传递请求,则无需在此处进行模拟.

[TestMethod]
public void Should_return_a_valid_json_result() {
    // Arrange
    var search = new Search();
    search.Area = "test";
    var json = JsonConvert.SerializeObject(search);

    var request = new HttpRequestMessage();
    request.Method = HttpMethod.Post;
    request.Content = new StringContent(json);

    var controller = new UserController();
    controller.Request = request;

    //more code

}

我正在使用这种方法

        var json = JsonConvert.SerializeObject(request);
        var stream = new MemoryStream(Encoding.UTF8.GetBytes(json));
        var httpContext = new DefaultHttpContext()
                              {
                                Request = { Body = stream, ContentLength = stream.Length }
                              };
        var controllerContext = new ControllerContext { HttpContext = httpContext };            

        var controller = new Your_Controller(logic, logger) { ControllerContext = controllerContext };
