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。
解决方法
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); }
