• When we discover a bug, have Christopher write a test script that reproduces it and fails.
• When the developers fix the bug, either JoAnn? or Christopher re-run the test script and verify that it now passes.
  • "developers" could include an outsourced developer. Just send them the failing test case(s) and tell them to make it work.
• Over time, these scripts will grow more and more comprehensive.
• Before we do any release, we run all test scripts on several clients' databases to prove that we haven't reintroduced any old bugs.
