I was mostly referring to integration tests. And yes, there are basics like fixtures which do get DRY'd out but they really need to be as unambiguous as possible in their mental model `insert(<table>,[<c:v>])` for a database entry, e.g.

I guess my point was not that you never DRY in tests, just that you should be very picky about when to DRY, more so than in code, and that is necessarily in opposition to the advice in OP.
