Unit testing serialization pre-membase

hey folks,

I've recently come across a problem with a complex domain object where it's no longer being cached by membase, and I can't (looking through all the properties/sub properties) see a good reason for it not caching - other objects are, so there isn't a server problem.

What I'd love to do with my code is write simple unit tests against each of my objects that I plan to use within membase to ensure that they *are* serializable, and if not, the test fails with the 'why not'.

I'm using the default transcoder.

At the moment I have:

[Test]
public void MyUser_ShouldBeSerializable()
{
MyUser user = new MyUser();
MemoryStream mem = new MemoryStream();
BinaryFormatter b = new BinaryFormatter();
try
{
b.Serialize(mem, user);
}
catch (Exception ex)
{
Assert.Fail(ex.Message);
}
}

now according to this, it serializes fine (the test passes) so I guess membase (and the enyim client) aren't using the binary formatter to serialize the object.

Can anyone shed any light on what type of serialization I should be testing against to ensure I'm testing my objects against the default transcoder/serializer within membase?

Many thanks,
Terry
