Serialization of Derived Class - MS Test Passes 'Debug', Fails 'Run'

[jehugaleahsa]

I have a base class called DataObject:

[Serializable]
public abstract class DataObject
{
/* Methods only */
}

[Serializable]
public class Customer : DataObject, ICustomer
{

}

My tests use MemoryStream and BinaryFormatter to tests the
serialization. Something like this:

using (MemoryStream stream = new MemoryStream())
{
BinaryFormatter formatter = new BinaryFormatter();
formatter.Serialize(stream, customer);
stream.Position = 0;
Customer copy = (Customer) formatter.Deserialize(stream);
}

I am using MS' Team System Tester. When I 'Run' these tests, I get an
error claiming that DataObject is not marked serializable. But, if I
'Debug' these tests, they all pass.

It is almost as if testing tool has a bug in it. Is there a reason my
code would work when I 'Debug' it? I also noticed that after the first
'Debug', subsequent 'Run' pass.

Has anyone else run into this?

Maybe you should look into using Rhino Mocks to mock-up the DataObject,
MBUnit Framework and Gallio. Rhino Mocks and Gallio are Open source and
free, and MBUnit Framework comes with .NET.

I came in on Friday and started looking into this again. I about
killed myself when I saw my project was compiling in Release mode.

This is still probably a bug in the testing tools, but I doubt they
expected developers to be testing in release mode. I guess I'll give
myself the blame for this one.
