Theories Using Object Parameters Are Displayed As Single Test Cases in GUI and Do Not Provide Case in Results File

/cc @bradwilson can we just ToString() other types used in this context for the display names?

[bradwilson]

This is not about display names; this is about the fact that the theory data is not serializable.

[clairernovotny]

If the custom types implemented IXunitSerializable, would it work better?

[bradwilson]

Yes.

I wrote a wrapper object that implements the IXunitSerializable interface and that corrected this issue for me. Sorry for the bother. I partially modified code I saw Brad posted here: xunit/xunit#429

    public class MemberDataObject : IXunitSerializable
    {
        public MemberDataObject() { }  // Needed for deserializer

        public MemberDataObject(object pTestObject)
        {
            TestObject = pTestObject;
            TestObjectName = TestObject.GetType().Name;
        }

        public object TestObject { get; private set; }
        public string TestObjectName { get; private set; }

        public void Deserialize(IXunitSerializationInfo serializationInfo)
        {
            TestObject = serializationInfo.GetValue<string>("TestObjectName");
        }

        public void Serialize(IXunitSerializationInfo serializationInfo)
        {
            serializationInfo.AddValue("TestObjectName", TestObjectName);
        }

        public override string ToString()
        {
            return TestObjectName + "()";
        }

        public T GetObject<T>()
        {
            if (TestObject is T)
                return (T)TestObject;
            else
                return default (T);
        }
    }

Edit: Copied the wrong implementation; that one had errors. This one works.

Thanks, closing this out then.
