Bug 15777 - Fix base class to prove refactor and fix required

TEST PLAN
---------
1) Apply the testing patch and this patch
2) prove -v t/RecordProcess.t
   -- will complain about string use with "use strict".
      This is because it is using the module name, instead
      of the object instantiated with new().
3) run koha qa test tools.
