You can easily implement such a setup by placing the module versions into a separate dir and then adding the right version dir to you sys.path before test startup. E.g. export PYTHONPATH=mymodule/3.0; python test.py export PYTHONPATH=mymodule/3.1; python test.py >> I have client code in multiple projects using version x.y of a C-compiled >> module A. >> >> I want to test a new version x.z of module A, but all client software >> needs >> to be recompiled against the new version.
