# This setup is drawn from Astropy and might not be entirely relevant to us;
# in particular we don't have a cron run for slow tests.

# Tell Hypothesis that we might be running slow tests, to print the seed blob
# so we can easily reproduce failures from CI, and derive a fuzzing profile
# to try many more inputs when we detect a scheduled build or when specifically
# requested using the HYPOTHESIS_PROFILE=fuzz environment variable or
# `pytest --hypothesis-profile=fuzz ...` argument.
