# We want to be able to really read a file during a recipe test. Of course,
# we want to prevent recipe authors from reading files that only exist on
# their own local disk (e.g. any file in some other repository), so that a
# test only reads files that are guaranteed to be available wherever the test
# is run (and by whomever runs it).
# Therefore we only allow a real file to be read when it's in the same repo
# as the recipe.
# In order to enforce this, we accept a relative path and join it to the
# location of build... determined by the relative location of this file in
# the build repo on the user's local disk.
# This script currently lives at scripts/slave/recipe_modules/file/test_api.py.
# If you ever change that, you must update the path below.
