This imports something from the parent dir of the script file in a very nasty way.

nope.py

# This is some butt ugly fuckery that basically chdirs to the
# directory that is parent to this source file, imports the
# test subject from the main script, then de-imports (not really
# cause Python doesn't support that) the stuff that it needed to
# do that as not to pollute the name space and cause tests to
# possibly fail because of that.
#
# In order for this to work it's imperative that you:
#   - Have the main script on the parent directory to the one
#     this script file is in.
#   - Don't use a weird naming scheme for things (slashes and stuff),
#     don't abuse symlinks near this project, be wary about the file
#     structure of the project.
#   - Understand that even though you may have taken care of the
#     above, it still may fail because this is some mind boggling
#     hackery, and this kind of fuckery doesn't come with a warranty.
#
# I am not particularly proud of this code, but it works like a charm.
# Kind of like speeding on an empty highway... With malfunctioning brakes.
