Your main script (or the testing code) is a program, it uses (i.e. imports) the library. I usually put the test code or the main entry point one level above the package in the development environment. This way, "import testpackage" works almost the same as it would in the production environment (where the package is installed, probably in site-packages) -- Gabriel Genellina -- http://mail.python.org/mailman/listinfo/python-list
