Georg Lauterbach f496897b09 test helpers: add functionality for sending emails (#3026) ... * add functionality for filtering mail log by ID This was not planned, but as @polarthene mentioned in https://github.com/docker-mailserver/docker-mailserver/pull/3033#issuecomment-1407169569 , filtering the mail log by email ID would be (the only) correct approach for the Rspamd test (to eliminate race conditions). I asserted the currect state, and came to the conclusion that this might (or actually is) something we want in more than one place. So I went ahead and implemented a solution. The solution for acquiring the ID is a bit slower because it ensures the mail queue is empty _before_ and _after_ the mail is sent. This is the tradeoff one has to make if they want to send multiple emails in one test file and get their IDs. I hope you like this approach. I will provide another PR that adjusts our current tests to use these new functions. * added note about our helper functions in the docs I think our work for our custom test framework should be noted in the docs for newcomers to better understand what they should do. * adjust Rspamd test to use new helpers for sending * improve filter helpers further * add sanity check when acquiring mail ID * re-add `refute_output` to test which should now work well		2023-01-29 14:52:38 +01:00
