# Test the KiCad plugin regarding some expected features.

# 1) Build target _pcbnew after enabling scripting in cmake.
# $ make _pcbnew

# 2) Changed dir to pcbnew
# $ cd pcbnew
# $ pwd
# build/pcbnew

# 3) Entered following command line, script takes no arguments
# $ PYTHONPATH=. <path_to>/test_kicad_plugin.py
