# This file currently contains a few controller UTs
# I couldn't find where the current base tests are, so I created this file.
# If there aren't any base-specific UTs, then this file should grow as they
# are written. If there are, or there is a better place for these, then I will
# move them to the correct location.

# Provide a static version of the Controllers module instead of the auto-loading version.
# We don't want these tests to fail when dependencies are to blame.
