Source code for tests.remotedebug.basic_debug_calls.err_transparent.CallCase

"""
Verifies basic facilities for remote debugging by starting a subprocess.
Uses:

* epyunit.SystemCalls()

* epyunit.callit()

Applies a two-level subprocess stack:

0. This UseCase

1. The wrapper 'epyunit4RDbg.py'

2. The script with dummy responses for tests 'myscript.py'
