# We specify test-dependencies here (and have them loaded through `.setup_local_venv.sh`)
# because otherwise `pytest` won't be able to see the locally build python package!
#
# Extra notes:
#
# - We rely on `pytest-parallel` rather than `pytest-xdist`
# since we currently rely on `multiprocessing`'s `fork` strategy,
# which is incompatible
# since pytest-xdist always spawns threads internally
# c.f. https://docs.python.org/3/library/multiprocessing.html#contexts-and-start-methods
# - We need to specify `py` as extra requirement because of this issue: https://github.com/kevlened/pytest-parallel/issues/118
