@senny For your review. Thanks! I'll squash the commits once the review is done :)

I noticed that we were overriding the method teardown in ActiveRecord::TestCase where SQLCounter.clear_log is called.

[senny]

probably best to use the teardown helper method like so:

teardown do
# ...
end

This won't overwrite the normal teardown method and we can't forget to call super.

Please do squash the commits. You can always make further review changes using git commit --amend and git push -f afterwards.

[tgxworld]

Ok no problem. I wanted to show the commits first so that it will show the reviewer what I'm doing before squashing them.
