ASP.NET MVC3 generated test projects throw exception

Hi Chad,

Thanks for reporting about this issue.

Can you please post a code sample for the problem?
As a workaround until we'll fix the problem if you are not using the Isolator in this test you can disable it from the Typemock menu in Visual Studio.

Our policy for bug fixing is to send the users that found the issue a patch as soon as possible so they will not have to wait for the next release.
Also a bug is fixed only when the user who reported it says it's fixed and not when we think it's fixed :) so we want the user to use the patch before we are releasing a new version.

I don't really even have to send a sample.

Download the beta for MVC3 from http://www.microsoft.com/downloads/en/d ... bf300b2c51.

Create a brand new MVC product (File->New->Project->ASP.NET MVC 3 Web Application).

From the dialog, Select "Internet Application", and check the "Create a unit test project" checkbox.

Try and run the HomeControllerTest.Index() test and it will fail with the exception.

We do need to use typemock, as we need to mock access to our Model class library.

Hi Chad,

Thanks, we'll try that out and let you know the results.

Any update to this issue. Though we just typemock exclusively today, some of our management is starting to consider going elsewhere due to not being able to test our new code.

Hi Chad,

We reproduced the error you reported about and it seems that the it happens just because Isolator is injecting code. We contact MS folks to help us out with it.
I'll update you once we'll have an answer.

Hi all.
Do you have any updates to this issue?
We faced with this issue too.
Thanks.

Hi,

We are working to solve this problem now.
Hopefully there will be a patch ready this week.
We'll announce about it here once it will be ready.

Hi All,

We created a patch that should solve the problem for MVC3
You can download the patch from this link:
https://www.typemock.com/patches/Typemoc ... .6.355.msi

Please let us know if it solves the problem.

Hi Ohad,

After the patch all my issues were solved.
Thanks!

I am having this problem too.

I just installed version 6.0.7.0 about an hour again and I'm still getting this error.

So here's the rundown, we're using RIA System.ServiceModel.DomainServices dll.

The test I have isolating the issue works fine with the TypeMock dlls not included in the solution, but once I include them I get this error:

Error 1 Test 'GameFly.Enterprise.Retail.UnitTest.Validation.NastyGrossReflectionStuffTestFixture.TryValidate_ShouldNotThrowVerificationException' failed:

Here's my code, I know I have some nasty reflection stuff going on, I'm sorry but I need this code and i don't want to have to write code that does the same thing as this. Besides BOO to microsoft for hiding these gems from me. So yes, this is nasty not very maintainable code but I'm doing it and TypeMock is not playing nice with it.

[TestClass]
   public class NastyGrossReflectionStuffTestFixture {

      /// <summary>
      /// Please don't throw this error
      /// </summary>
      [TestMethod]
      public void TryValidate_ShouldNotThrowVerificationException() {

         var fBar = new FooBar
                  {
                     Name = "Captain FooBar!!!"
                  };


         var context = new ValidationContext(fBar, null, null);

         var assembly = typeof (DomainService).Assembly;
         var type = assembly.GetType("System.ServiceModel.DomainServices.Server.ValidationUtilities");
         var method = type.GetMethod("TryValidateObject", BindingFlags.Static | BindingFlags.NonPublic | BindingFlags.Public);

         var result = (bool) method.Invoke(method.DeclaringType.Module, new object[] {fBar, context, new List<ValidationResult>()});

         Assert.IsTrue(result);


      }

      public class FooBar {


         [Required(ErrorMessage = "The parent  name is required")]
         public string Name {
            get;
            set;
         }

      }
   }
