What I'm getting at from the name of this test, as well as what other tests below it is doing, is that this test tests for a keyboard that's not in a folder. therefore I believe the way to solve this is to find another keyboard that is unlikely to be moved into a folder(my candidate is crkbd) and substitute that

If anything, handwired/onekey would be a better solution, in that case.

If anything, handwired/onekey would be a better solution, in that case.

that would still fall into the "in a folder category" and be covered by the test_list_keymaps_vendor_kb case
