# A script to run tests on the Algorithm::Mukres module.
# The following are among the tests run by this script:
# This test case checks the module for negative input values.
# 1. Try loading the Algorithm::Munkres i.e. is it added to the @INC variable
# 2. Compare the lengths of the Solution array and the Output array.
# 3. Compare each element of the Solution array and the Output array.
