We could have test_ruby_unordered and sort both the expected and actual files to ensure the tests don't break if in the future the default order changes. But personally I don't see much point in complicating the tests preemptively. I would rather worry when the time comes, which might be never. -- Felipe Contreras _______________________________________________ notmuch mailing list -- firstname.lastname@example.org To unsubscribe send an email to notmuch-le...@notmuchmail.org
