That is trivial to do without any runtime flags. For example for
testing both the C and Python implementations of StringIO (and
BytesIO), I define the Python implementation with a leading underscore
and rename it if the C implementation is available:
 class _StringIO(TextIOWrapper):
 ...
 # Use the faster implementation of StringIO if available
 try:
 from _stringio import StringIO
 except ImportError:
 StringIO = _StringIO
With this way, the Python implementation remains available for testing
(or debugging). For testing the modules, I first check if the C
implementation is available, then define the test according to that --
just check out by yourself:
