Re: [development] Drupal & automated testing

medication. I agree, unit test are valuable. However, maintaining unit tests could be as difficult as building core itself initially.

I agree with Kieran here. Tests become part of the project, adding to its overall size. When there is a crunch for time or money, the tests get neglegted, and fall into disuse. This makes them totally useless, since things change over time, and the old tests are a) not enough to certify all new functions of the project, and b) old function behaviors have changed, and the tests no longer pass. So, only do automated tests if you are willing to put the time and effort to maintain them for the lifetime of the project.
