# Here's where we test assumptions about way Rails behaves that we
# rely on in the codebase. That way, if the Rails behaviour changes,
# we can catch the underlying cause here, which can save a good deal
# of bug chasing.

# This only works in the case where the article caches the comment
# counter. Because the counter_cache is 'invisible' to the model, it
# could be argued that incrementing it shouldn't go triggering the
# 'visible' save/update/whatever hooks in Activerecord. (Which would
# be a shame, because we rely on it). So, we'll continue to check
# that Rails does what we expect.
