asp.net-mvc – 单元测试ASP.NET MVC中的自定义模型绑定2

前端之家收集整理的这篇文章主要介绍了asp.net-mvc – 单元测试ASP.NET MVC中的自定义模型绑定2前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
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

修改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);
}
