QA Dept, cont

The problem comes when the programmers leave all testing to the QA folks
- long delay between causing the bug and finding the bug
- QA dept rarely can fix the bugs themselves
- Causes tension between QA dept and coders (as if they caused the bug)
- QA dept often can only test at a very high level

Programmers should write their own lower level automated tests
- Get the benefits of testing as you go

QA Dept should handle higher level acceptance tests
- Acceptance tests are often tricky
