Problem using Natural Mocks with Generics

Shawn,
Welcome to the forums,
You have found a bug :twisted: , thanks for reporting this and posting the code that reproduces the problem.

We will send you a fix offline.

The problem happens when the returned property is a Generic Type and the generic parameter is defined in the calling Type. TypeMock didn't know how to bind the types.

Great. Thanks for the quick reply. I'll try the patch when I get a chance.

Using typemock 3.7.1 and .Net 2.0 I am experiencing a similar problem when my generic type is a IList<object>. I get a different exception tho... Can you send me the patch as well if you think this is related?

System.IndexOutOfRangeException : Index was outside the bounds of the array.

Hi Matt
It doesn't look like its the same problem.
Can you post an example code that generates the error?

Here is a sample that will result in the exception:

    public class Temp1<T>
    {
        private T _result;

        public T Result 
        { 
            get { return _result; } 
        }
    }

    public class Temp2 : Temp1<List<string>>
    {
        
    }

    public class Temp3
    {
        public string DoSomething()
        {
            Temp2 myTemp2 = new Temp2();
            return myTemp2.Result[0];
        }

    }

    [TestFixture]
    public class Temp3Fixture
    {
        [TestFixtureSetUp]
        public void Setup()
        {
            MockManager.Init();
        }
        
        [TestFixtureTearDown]
        public void Teardown()
        {
            MockManager.Verify();
        }

        [Test]
        public void DoSomethingTest()
        {
            List<string> myResult = new List<string>(new string[] { "result1" });
            
            using (RecordExpectations recorder = new RecordExpectations())
            {
                Temp2 myTemp2 = new Temp2();
                recorder.ExpectAndReturn(myTemp2.Result, myResult);   

            }

            Assert.AreEqual("result1", new Temp3().DoSomething());
        }
    }

Hi Matt
Thanks for posting the example. You actually found a different bug.
We will fix it and send you the patch.

Hi Matt
I sent you the patch
Please check it and tell me if it works.
