Let's make the dropin, to make the build dir writable for gcov, a bit
more generic, so it can be used by all units starting with prefix test-.
This should help with a bunch of recent reports about missing coverage I
got, as well as with existing test units using DynamicUser=true.
This might feel a bit like a magic trick from behind the curtains, but I
want to touch the actual tests as little as possible, since it makes them
unnecessarily messy (see the various workarounds for sanitizers), and
the coverage reports are generated only in a specific CI job anyway.
"! test ..." does not cause the script to fail, even with set -e.
IIUC, bash treats this command as part of an expression line, as it
would if 'test ... && ...' was used. Failing expression lines do not
terminate the script.
This fixes the obvious cases by changing '! test' → 'test !'.
Then the inversion happens internally in test and bash will propagate
the failure.
