The tests in this directory take a very long time and require a specific environment to run.

Tests module unparsing of every file in the active python sys.path. If a minified unparsed module doesn't parse back into the original module, that test fails.

Minifies and executes files listed in a test manifest. Multiple combinations of options are tested, with additional options specified where necessary. A non zero exit code from a minified execution is a test failure.

The manifests directory contains manifests for testing the cpython/pypy regression tests on supported python versions.
