Tests work with hardcoded /tmp/xxx, leading to potential test failures
It appears that gcr tests create a /tmp/xxx
via gcr/fixtures/gnupg-mock/mock-fail-signal
script.
Please consider moving to a more unique name, perhaps via mktemp or other means.
I hit a problem with it due to running tests under different users, so the /tmp/xxx was leftover under one users permissions when the next try with other user failed to overwrite it, leading to prompt test failures
