A Safer Mailbox Lease for CI Automation

Описание и применение

Внедрение аренды почтовых ящиков в CI устраняет непредсказуемость тестов, обеспечивая явную собственность, контроль времени и надёжную очистку.

Задача

Email tests become unreliable when CI pipelines treat inboxes as permanent shared resources, leading to random failures due to ownership ambiguity.

Результат

Implementing mailbox leases reduces flaky email tests, provides clear ownership, and enables reliable cleanup, improving CI stability.

Рабочий процесс

• Create a mailbox lease record with run ID, suite, address reference, and timestamps.
• Use the lease address for email actions (signup, reset, notification).
• Poll for expected events while recording state transitions.
• On test completion or failure, run cleanup: release or expire the lease.
• Collect a compact evidence bundle (manifest, event IDs, timestamps, failure category).

Доказательства

Email tests become unreliable when every pipeline treats the inbox as a permanent shared resource.

Источник

A useful mental model is a mailbox lease. A CI run temporarily owns an isolated disposable address, records why it exists, and gives it back when the run ends.

Источник

The lease model gives each run four simple answers: Who owns this inbox? Why was it created? How long is it valid? What happened to it?

Источник

Cleanup should run from a finally path or an equivalent CI post-job hook. It must be safe to call twice.
