# Test Evidence: Sanitized production mail exception feedback

- **Test type:** Web
- **Requirement IDs:** `INT-005`, `INT-008`
- **Scenario IDs:** `AC-INT-002` (production mail-failure boundary)
- **Test class/method:** `com.lab.labtimesheet.feature.integration.controller.SmtpOnboardingWebIntegrationTest#failedSmtpTestRendersActionableFeedbackWithoutActivatingTheDraft`
- **Implementation commit:** `pending`

## Protected behavior

Spring Mail delivery failures from the production SMTP adapter return the fixed Admin guidance instead of escaping
the MVC request or exposing provider diagnostics. A failed probe does not mark the draft tested or enable activation.

## Test method

MockMvc saves a valid draft, then the test SMTP boundary throws Spring's production-shaped `MailSendException` with a
distinctive deterministic diagnostic. The authenticated CSRF-protected request crosses the real controller and SMTP
configuration service, and the rendered Thymeleaf response is inspected for the fixed message, raw-text absence, and
absence of the activation action.

## Hand-derived expected result

The response is HTTP 200 on `smtp/form`, contains the fixed operator guidance, omits the exception diagnostic, and
does not offer Activate SMTP because `markTested` was never reached.

## External-test boundaries

The test exercises the production Spring Mail exception type without contacting an external SMTP server. It does not
prove live Mailpit/provider interoperability and contains no real credential or activation token.
