Make Playwright Email Tests Explain Their Waits

Описание и применение

Тесты Playwright, проверяющие электронную почту, часто завершаются общим таймаутом, скрывая причину. В статье предлагается использовать ограниченный «проб» для проверки почтового ящика, фиксировать состояние, таймстемпы и диагностические данные, а затем сохранять их как JSON‑артефакт для последующего анализа.

Задача

Email verification tests in Playwright often fail with a generic timeout error, hiding the root cause of why the message was not found.

Результат

The test now reports explicit mailbox states, timestamps, and observed subjects, turning a vague timeout into actionable diagnostics.

Рабочий процесс

• Allocate a unique inbox address using the inbox client.
• Generate a correlation token and record the trigger timestamp.
• Invoke a bounded probe that polls the inbox at fixed intervals until a deadline.
• Return a ProbeResult indicating matched or timed‑out state and the subjects seen.
• Attach the probe result, address, token, and request ID to the Playwright test as a JSON artifact.
• Use the artifact to correlate browser actions, server logs, and inbox data for debugging.

Доказательства

Email verification tests often fail in a confusing way: the browser is on the right page, the message eventually arrives, and the test still reports only Timeout 30000ms exceeded.

Источник

The probe should poll at a fixed interval, stop at a deadline, and return the messages it saw.

Источник

Attach the probe result to the Playwright test, along with the allocated address, correlation token, and trigger timestamp.
