# This script downloads the test files from the build bucket and makes some executable.

# OS_ARCH: The operating system and the architecture separated by a hyphen '-' (e.g. darwin-amd64, linux-amd64, windows-amd64)
# VM_DRIVER: the vm-driver to use for the test
# EXTRA_START_ARGS: additional flags to pass into minikube start
# EXTRA_ARGS: additional flags to pass into minikube
# JOB_NAME: the name of the logfile and check name to update on github
# PARALLEL_COUNT: number of tests to run in parallel
