Question

我目前正在尝试测试使用TryUpdateModel（）的插入方法。我正在伪装控制器上下文，这是必要的，虽然这样做似乎没有发布我已经设置的模型。

以下是我正在测试的方法：

 [AcceptVerbs(HttpVerbs.Post)]
    [GridAction]
    public ActionResult _SaveAjaxEditing(int? id)
    {
        if (id == null)
        {
            Product product = new Product();
            if (TryUpdateModel(product))
            {
                //The model is valid - insert the product.
                productsRepository.Insert(product);// AddToProducts(product);
            }
        }
        else
        {
            var recordToUpdate = productsRepository.Products.First(m => m.ProductID == id);
            TryUpdateModel(recordToUpdate);
        }
        productsRepository.Save();
        return View(new GridModel(productsRepository.Products.ToList()));
    }

这是我目前的测试：

        [TestMethod]
    public void HomeControllerInsert_ValidProduct_CallsInsertForProducts()
    {
        //Arrange
        InitaliseRepository();

        var httpContext = CustomMockHelpers.FakeHttpContext();
        var context = new ControllerContext(new RequestContext(httpContext, new RouteData()), controller);
        controller.ControllerContext = context;
        //controller.ControllerContext = new ControllerContext();

        var request = Mock.Get(controller.Request);
        request.Setup(r => r.Form).Returns(delegate()
                                               {
                                                   var prod = new NameValueCollection
                                                                  {
                                                                      {"ProductID", "9999"},
                                                                      {"Name", "Product Test"},
                                                                      {"Price", "1234"},
                                                                      {"SubCatID", "2"}
                                                                  };
                                                   return prod;
                                               });


        // Act: ... when the user tries to delete that product
        controller._SaveAjaxEditing(null);
        //Assert
        _mockProductsRepository.Verify(x => x.Insert(It.IsAny<Product>()));
    }

正在调用该方法但是当它到达TryUpdateModel（）时，它似乎无法拾取已发布的对象。关于我出错的地方的任何指示都会很棒。

对它进行排序。似乎嘲弄Httpcontext完全是过度的。

controller.ControllerContext = new ControllerContext();

var prod = new FormCollection
            {
                {"ProductID", "1"},
                {"Name", "Product Test"},
                {"Price", "1234"},
                {"SubCatID", "2"}
            };

controller.ValueProvider = prod.ToValueProvider();

这就是诀窍。它现在已发布。

使用MStest和moq测试TryUpdateModel（）
