You are right.

And if you want to assertEqual(a, b) to capture a and b,
you need to replace assertEqual to forward the values to
your own failureException.

I guess we will go this way: replace failureException and
assertEqual(), assertIn(), .... 

No change in Python's unittest lib is needed.

Thank you for your reply.
