AGENTS.md notes get_dmarc_reports_from_mailbox was halted at low coverage
because honest testing needed a live IMAP server or mocks so deep they test
the mock. mailsuite's MaildirConnection is a real on-disk backend with no
network or credentials, so the fetch -> parse/classify -> route loop can now be
exercised for real in CI.
TestGetDmarcReportsFromMailboxMaildir delivers real sample reports (one
aggregate, failure, and SMTP-TLS email) plus an unparseable message into a
Maildir INBOX, runs get_dmarc_reports_from_mailbox offline, and asserts on
observable results — parsed report counts and which archive subfolder each
message physically lands in:
- each report type routed to Archive/{Aggregate,Failure,SMTP-TLS}, the junk
message to Archive/Invalid, INBOX drained
- delete=True removes processed messages instead of archiving them
- test=True parses and returns reports but moves nothing and creates no folders
setUp resets the module-global SEEN_AGGREGATE_REPORT_IDS dedup cache so test
order can't drop an already-"seen" aggregate report, and the maildir lives at a
fresh subpath so mailbox.Maildir(create=True) actually builds cur/new/tmp.
Lifts parsedmarc/__init__.py from 76% to 82%, honestly.
