# testdirs: align test name and assertion with the documented invariant

Follow-up review feedback on #1411: rename the test (it no longer
asserts "never under home") and compare against the real app dirs
(~/.config/entire, ~/.cache/entire) rather than their parents — TMPDIR
is commonly set under $HOME/.cache, which is legitimate.
