# This spec file is one part of a two-part strategy to maintain data integrity. The first part
# is to proactively protect data integrity using database constraints (not null, foreign keys,
# etc) and ActiveRecord validations. As a backup to those two techniques, and particularly in
# the cases where it's not possible to model an integrity concern with database constraints,
# we can add a reactive integrity test here.

# These tests are run nightly and the results are emailed to the MAILTO address in
# config/schedule.rb if any failures occur.
