# - Runs pytest with the required environment to run tests on an x-d-p build
# - By default, the tests run on the first x-d-p build directory that is found
#   inside the source tree
# - The BUILDDIR environment variable can be set to a specific x-d-p build
#   directory
# - All arguments are passed along to pytest
# - Check tests/README.md for useful environment variables
#
# Examples:
#
#   ./run-test.sh ./test_camera.py -k test_version -v -s
#
#   BUILDDIR=../_build ./run-test.sh ./test_usb.py
