# It used to be this script that held the shape of the testing: a list of eight
# invocations of one monolithic program with different flags, plus a second script for
# another directory, plus a handful of scripts nothing called at all. The combinations
# are the interesting part of this suite, so they live in the test code as parameters
# now — which is what lets a case this host cannot carry be skipped rather than failed,
# and lets one failure name its own combination instead of ending the run.
#
# What is left here is what a shell script is actually for: install the dependencies,
# wait for the instance to answer, and hand over to pytest. Every argument is passed
# straight through, so anything pytest understands works here:
#
#   ./run_tests.sh                              # everything, against the default instance
#   ./run_tests.sh --set-pass                   # set the password first, as CI does
#   ./run_tests.sh mypassword                   # a different password
#   ./run_tests.sh -k udp                       # just the UDP tests
#   ./run_tests.sh unit                         # the ones needing no instance
#   ./run_tests.sh --layer proxy --no-ipv6 -x   # narrow, and stop at the first failure
