# This file should be executed from tox, as the assumend working directory
# is different from where this file is located.
# This file does not have executable flag nor shebang,
# to dissuade non-tox callers.
# This script starts with copying ${CSIT_DIR}/tests to ${GENERATED_DIR}/.
# Then the script runs every executable *.py script anywhere in the copied dir,
# the working directory temporarily changed to where the *.py file is.
# Proper virtualenv is assumed to be active.
# Then another directory in ${GENERATED_DIR} is created, where
# the just generated content is copied and then overwitten by the non-generated.
# If "diff -dur" sees any changes by the overwrite, this script fails.
# The diff output is stored to autogen.log (overwriting).
# The executed *.py files are assumed to be robot suite generators,
# any change means the contribution is not consistent with the regenerated code.
# "set -eu" handles failures from the following two lines.
