# Utility to help running in-docker tests in the same conditions as CI (Gitlab)

# example:
# ./scripts/run_docker_test.sh docker/Dockerfile.debian.testing \
#                             -eTEST_BUILD_DIR=build-openssl11 \

#                             -eTEST_TESTSUITE_ONLY=crypto \
#                             -eTEST_WITH_STATICTESTS=1 \
#                             -- ./scripts/test.sh

# ./scripts/run_docker_test.sh docker/Dockerfile.debian.testing
