Well, implementing fall-backs would undermine the idea to simplify the
implementation of test scripts.

Even the main test scripts wouldn't be shell scripts anymore. One would
use an unit testing framework for that scripting language and implement
test classes for the specific tests. Invoking shell commands can be
easily implemented by Python module subprocess (see
http://docs.python.org/library/subprocess.html#module-subprocess).

Simple example in the code of the MoinMoin project:

Ciao, Michael.
