Testing and QA

Have been plagued by more errors than are worth listing. The one recurring error message I'm receiving may hopefully be the clue to fixing our system. But I have no idea what to do with this error message - i.e. how to fix it. Many processes trigger this same error, but in this specific case, it was running Unit Tests.

The error message:

[21-Sep-2011 19:32:43] PHP Notice: Did you remember to make the first column something unique in your call to get_records? Duplicate value '1' found in column 'id'.
