Some tests (e.g. mail) have expensive and significant DB setup for a
number of small and cheap tests. Using a TransactionCase, the DB setup
far dominates the tests themselves, by up to 10x (mail unit tests take
~130s on my machine, the tests themselves take ~15s).
The SavepointCase introduced here is an hybrid of SingleTransactionCase
and TransactionCase: it uses a single transaction for all tests in a
class, but each test case is isolated by a rollbacked savepoint. This
allows a common DB setup (via setUpClass) while keeping independent
tests.
TransactionCase should remain the primary test case superclass, but
SavepointCase can be a fair optimisation when setup costs far dominate.
Replaced some read by browse
Moved get_reply_to from mail_mail to mail_message
Hint: specifying email_from, reply_to help to enhance computation time
[REF] mail: cleaned some tests, renamed a file, moved mail_group tests into a dedicated file
