Question

我试图模拟我的控制器来测试模型状态是否无效，如果模型状态无效，单元测试基本上会返回400错误。但模型状态在Model Binder的 BindModel （）方法中得到验证。通过单元测试，我无法点击 BindModel （）方法。

我有一个通用的方法来模拟下面显示的Controller方法：

public static async Task<HttpResponseMessage> MockController<T, 
TReturn>(
       this T controller, Func<T, Task<TReturn>> func, string requestUri = 
"http://tempuri.org", HttpMethod httpMethod = null) where T : ApiController
        {
          using (var request = new HttpRequestMessage(httpMethod ?? HttpMethod.Get, new Uri(requestUri)))
            {
                controller.Request = request;

                var actionResult = await func.Invoke(controller);
                // Create the response from the action result
                if (typeof(IHttpActionResult).IsAssignableFrom(typeof(TReturn)))
                {
                    return await ((IHttpActionResult)actionResult).ExecuteAsync(CancellationToken.None);
                }
                else
                {
                    return await Task.FromResult(request.CreateResponse(actionResult));
                }
            }
        }

以上方法如下所示：
param无效

param=new someclass
{
    Data1=new List{"abc"}
};
var response = await controller.MockController(async c =>
{
    actionResult = await c.PostData(param);
    return actionResult;
});
Assert.AreEqual(HttpStatusCode.BadRequest, response.StatusCode);

我应该在MockController方法中进行哪些更改来调用BindModel传递的控制器类的方法？

        public class MyModelBinderProvider : ModelBinderProvider
        {
            public override IModelBinder GetBinder(HttpConfiguration configuration, Type modelType)
            {
                return new MyModelBinder();
            }
        }

        public class MyModelBinder : IModelBinder
        {
            public bool BindModel(HttpActionContext actionContext, ModelBindingContext bindingContext)
            {
                var requestJson = actionContext.Request.Content.ReadAsStringAsync().Result;
                var domain = actionContext.ActionArguments["domain"].ToString();

                try
                {
                    var model = Configuration.Load(requestJson);
                    bindingContext.Model = model;
                    domain = Map.GetEntityName(domain.Replace('-', '_'));

                    var invalidReqFieldsDict = RequestValidator.Validate(domain, model);
                    if (invalidReqFieldsDict.Any())
                    {
                        var exceptionMessage = String.Join("", invalidReqFieldsDict);
                        bindingContext.ModelState.AddModelError(bindingContext.ModelName, exceptionMessage);
                        return false;
                    }
                    return true;
                }
                catch (JsonException e)
                {
                    bindingContext.ModelState.AddModelError(bindingContext.ModelName, e.Message);
                    return false;
                }
            }
        }

非常感谢任何帮助！感谢
