我在项目中编写了自定义模型绑定器，它使用ASP.NET MVC 2.该模型绑定绑定只有两个模型字段：
public class TaskFormBinder : DefaultModelBinder
{
protected override void BindProperty(ControllerContext controllerContext,ModelBindingContext bindingContext,PropertyDescriptor propertyDescriptor)
{
if (propertyDescriptor.Name == "Type")
{
var value = bindingContext.ValueProvider.GetValue("Type");
var typeId = value.ConvertTo(typeof(int));
TaskType foundedType;
using (var nhSession = Domain.GetSession())
{
foundedType = nhSession.Get<TaskType>(typeId);
}
if (foundedType != null)
{
SetProperty(controllerContext,bindingContext,propertyDescriptor,foundedType);
}
else
{
AddModelBindError(bindingContext,propertyDescriptor);
}
return;
}
if (propertyDescriptor.Name == "Priority")
{ /* Other field binding ... */
return;
}
base.BindProperty(controllerContext,propertyDescriptor);
}
}
我如何使用标准的VS单元测试来测试这个模型的粘合剂？花了几个小时的谷歌搜索，找到几个例子(http://www.hanselman.com/blog/SplittingDateTimeUnitTestingASPNETMVCCustomModelBinders.aspx)，但这个例子是针对MVC1，并且在使用MVC2时不工作。
我感谢您的帮助。

我修改了
Hanselman’s MVC 1 example来测试ASP.Net MVC 2模型绑定器…
[Test]
public void Date_Can_Be_Pulled_Via_Provided_Month_Day_Year()
{
// Arrange
var formCollection = new NameValueCollection {
{ "foo.month","2" },{ "foo.day","12" },{ "foo.year","1964" }
};
var valueProvider = new NameValueCollectionValueProvider(formCollection,null);
var modelMetadata = ModelMetadataProviders.Current.GetMetadataForType(null,typeof(FwpUser));
var bindingContext = new ModelBindingContext
{
ModelName = "foo",ValueProvider = valueProvider,ModelMetadata = modelMetadata
};
DateAndTimeModelBinder b = new DateAndTimeModelBinder { Month = "month",Day = "day",Year = "year" };
ControllerContext controllerContext = new ControllerContext();
// Act
DateTime result = (DateTime)b.BindModel(controllerContext,bindingContext);
// Assert
Assert.AreEqual(DateTime.Parse("1964-02-12 12:00:00 am"),result);
}
