# This clears several environment variables and sets them to ephemeral
# values: a temporary database, temporary Nix store, temporary Hydra
# data directory, etc.
#
# Note: This function must run _very_ early, before nearly any Hydra
# libraries are loaded. To use this, you very likely need to `use Setup`
# and then run `test_init`, and then `require` the Hydra libraries you
# need.
#
# It returns a tuple: a handle to a temporary directory and a handle to
# the postgres service. If either of these variables go out of scope,
# those resources are released and the test environment becomes invalid.
#
# Look at the top of an existing `.t` file to see how this should be used
# in practice.
