Okay, then maybe a better example would be a command-line program like `grep` or `sed`. Should those be tested in a nursing home? I'd argue that's the wrong audience, and testing there would cause you to simplify these tools to a point where they're no longer useful.

(I do think it's notable that you can combine the inputs and outputs of such programs into a shell script, which feels a lot like using a programming language—but this is beside the point I was trying to make.)
