Cómo probar Carpetas de modelo personalizadas en ASP.NET MVC?

Question

He escrito algunos archivos de carpetas personalizados (que implementan IModelBinder) en nuestra aplicación ASP.NET MVC. Me pregunto ¿cuál es un buen enfoque para probarlos (carpetas)?

Answer 1

lo hice de esta manera:

var formElements = new NameValueCollection() { {"FirstName","Bubba"}, {"MiddleName", ""}, {"LastName", "Gump"} };   
var fakeController = GetControllerContext(formElements); 
var valueProvider = new Mock<IValueProvider>();   

var bindingContext = new ModelBindingContext(fakeController, valueProvider.Object, typeof(Guid), null, null, null, null); 



private static ControllerContext GetControllerContext(NameValueCollection form) { 
    Mock<HttpRequestBase> mockRequest = new Mock<HttpRequestBase>(); 
    mockRequest.Expect(r => r.Form).Returns(form); 

    Mock<HttpContextBase> mockHttpContext = new Mock<HttpContextBase>(); 
    mockHttpContext.Expect(c => c.Request).Returns(mockRequest.Object); 

    return new ControllerContext(mockHttpContext.Object, new RouteData(), new Mock<ControllerBase>().Object); 
} 

Y entonces me acaba de pasar en la variable BindingContext al método bindModel del objeto que implementa la interfaz IModelBinder.

Aquí está una manera simple sin burla que escribí para ti en mi blog suponiendo que el uso del ValueProvider y no HttpContext: http://www.hanselman.com/blog/SplittingDateTimeUnitTestingASPNETMVCCustomModelBinders.aspx

[TestMethod] 
public void DateTime_Can_Be_Pulled_Via_Provided_Month_Day_Year_Hour_Minute_Second_Alternate_Names() 
{ 
    var dict = new ValueProviderDictionary(null) { 
      { "foo.month1", new ValueProviderResult("2","2",null) }, 
      { "foo.day1", new ValueProviderResult("12", "12", null) }, 
      { "foo.year1", new ValueProviderResult("1964", "1964", null) }, 
      { "foo.hour1", new ValueProviderResult("13","13",null) }, 
      { "foo.minute1", new ValueProviderResult("44", "44", null) }, 
      { "foo.second1", new ValueProviderResult("01", "01", null) } 
     }; 

    var bindingContext = new ModelBindingContext() { ModelName = "foo", ValueProvider = dict }; 

    DateAndTimeModelBinder b = new DateAndTimeModelBinder() { Month = "month1", Day = "day1", Year = "year1", Hour = "hour1", Minute = "minute1", Second = "second1" }; 

    DateTime result = (DateTime)b.BindModel(null, bindingContext); 
    Assert.AreEqual(DateTime.Parse("1964-02-12 13:44:01"), result); 
}

dict podría ser reprogramado como esto

  FormCollection form = new FormCollection 
            { 
             { "month1", "2" }, 
             { "day1", "12" }, 
             { "year1", "1964" }, 
             { "hour1", "13" }, 
             { "minute1", "44" }, 
             { "second1", "01" } 
            }; 

      var bindingContext = new ModelBindingContext() { ModelName = "foo", ValueProvider = form.ToValueProvider() };
