# cvtestutils.py
#
# This module is meant to aid writing and running Python-based tests
# within the OpenCV tree.

#
# Upon importing, this module adds the following python module
# directories from the dev tree to sys.path (i.e. PYTHON_PATH):
# opencv/interfaces/swig/python and opencv/lib
#
# Using it in a test case is simple, just be sure to import
# cvtestutils before cv, highgui, etc
#
# Usage:
# import cvtestutils
# import cv
import os
import imp
import sys
