Study the traceback! This is in IDLE, not in unittest. self.text is
None. 

This happens when somebody closes sys.stdout, in IDLE: future writes
to sys.stdout fail. Now, I cannot guess why sys.stdout was closed in
your case; you should modify IDLE to raise an exception in close, to
see where the close originates from.
