[DISCUSS] Questions: testing compatibility test with older version on a POJO

[Clebert Suconic]

I need to write a test where the binary output would need to be
checked against an older version of a class.


The test would be something like:


{
   MessageImpl currentMessage = new MessageImpl();
   setProperties(currentMessages); // some method that will generate
data on message

   // something that will encode the message
   currentMessage.encode(someBuffer);

   osgiMagic(someBuffer);
}

I'm looking for some OSGI Magic where I can then make comparissons
with MessageImpl from 1.5.0.


Is there any manageable way of doing this? Manageable = not so bad
that only me would understand the code.


I don't even know what to look for on google, hence the question here.



thanks for any help is appreciated!
