FuelPHP Forums

I found a few problems in DBUtil::modify_fields. I have fixed them and would like to submit a pull request with tests. The problem is I have no idea how to write the test. All the functions in DBUtil end with something like:

\DB::query($sql, \DB::UPDATE)->execute();

So how can I examine the sql in a test? As is now probably obvious I am not awesome at php and may have missed something obvious.
