# This script parses the validation layers test continuous integration ouput
# and reports the number of tests that passed, failured, ouput unexpected errors,
# or were skipped. As such, the script is only designed to parse the ouput
# generated by the existing CI implementation.
#
# usage:
# for profile in tests/device_profiles/*.json; do echo Testing with
# profile $profile; VK_LAYER_PATH=DEVSIM_AND_VALIDATION_PATHS
# VK_DEVSIM_FILE=$profile VK_ICD_FILENAMES=MOCK_ICD_PATH
# ./build/tests/vk_layer_validation_tests --devsim; done
# | python3 parse_test_results.py [--fail_on_skip] [--fail_on_unexpected]
#
# --fail_on_skip causes the script to exit with a non-zero exit code if a test
# didn't run on any device profile
#
# --fail_on_unexpected causes the script to exit with a non-zero exit code if
# a test printed unexpected errors
