# DESCRIPTION
# This script runs tests defined in meta/lib/oeqa/selftest/
# It's purpose is to automate the testing of different bitbake tools.
# To use it you just need to source your build environment setup script and
# add the meta-selftest layer to your BBLAYERS.
# Call the script as: "oe-selftest -a" to run all the tests in meta/lib/oeqa/selftest/
# Call the script as: "oe-selftest -r <module>.<Class>.<method>" to run just a single test
# E.g: "oe-selftest -r bblayers.BitbakeLayers" will run just the BitbakeLayers class from meta/lib/oeqa/selftest/bblayers.py
