docs(quick-260907-let): Verbindungstest fuer das Postfach — Plan, Bericht, Verifikation
Abschluss-Dokumentation zum nachgeruesteten Verbindungstest (WINDOWS #16).

Verifikation unabhaengig nachgemessen, nicht aus dem Ausfuehrungsbericht
uebernommen: 646/646 API-Tests, 228/228 Web-Tests, beide Typpruefungen
sauber, und das Sprachschluessel-Gate ist von rot ("de fehlt testConnection")
auf gruen gewechselt. Sicherheitsseitig geprueft: die DTO traegt kein
Eigentuemer-Feld, der Handler zieht userId ausschliesslich aus dem
Auth-Kontext (eigener IDOR-Test mit Koeder-userId), Rueckfall auf gespeicherte
Zugangsdaten sucht nur ueber denselben userId, und in den geaenderten Dateien
findet sich keine Log- oder Antwortstelle mit Zugangsdaten.

Status bleibt human_needed: die Browser-Abnahme gegen ein echtes Postfach
steht aus und braucht einen Neubau durch den User. WINDOWS #16 bleibt
deshalb offen.

Ausserdem workflow.use_worktrees auf false: origin/HEAD ist in diesem Repo
nicht aufloesbar, der Basis-Check des Workflows verlangt daher selbst
sequenzielle Ausfuehrung ("fork-ref-unknown"). Ein isolierter Arbeitsbaum
wuerde von einem veralteten Stand abzweigen.

testConnection backfills BOTH username and password independently from stored, decrypted credentials — broader than saveConfig's credChanged branching, since a fully-blank test-connection form needs both fields, not just the one the caller didn't touch on a partial re-save.
Route-order comment corrected to state the accurate reason: NestJS resolves routes per HTTP verb, so a GET :id placeholder cannot shadow this POST route today. Ordering is defensive consistency with the surrounding email-config handlers, not a live 404 risk.
A per-user connection-test endpoint (userId from extractTriageContext, never the body) is now the second instance of this pattern after DkvController.testConnection — a template for any future per-user inbox-config module.

Quick Task 260907-let: Verbindungstest fuer das Postfach unter "Meine Quellen" Summary

POST /modules/tender-radar/email-config/test wires the already-existing ImapProvider/ExchangeInboxProvider.testConnection into a per-user endpoint, plus a "Verbindung testen" button in EmailAlertConfigForm — closes WINDOWS #16.

Performance

  • Duration: ~25 min
  • Completed: 2026-09-07T13:44:17Z
  • Tasks: 2
  • Files modified: 10

Accomplishments

  • Backend: TenderEmailConfigService.testConnection(userId, dto) — types in the DTO's password go straight to the provider; a blank username or password independently falls back to this same user's stored, decrypted credentials; dto.protocol === 'exchange' selects the Exchange provider, everything else IMAP.
  • POST /modules/tender-radar/email-config/test on TendersController — userId comes exclusively from extractTriageContext(req), proven by a dedicated IDOR test where the body carries a decoy userId field that never reaches the service call.
  • Declaration-order guard extended to cover testEmailConnection alongside the existing getEmailConfig/saveEmailConfig entries, so a future reshuffle above @Get(':id') fails the test immediately.
  • Frontend: "Verbindung testen" button in EmailAlertConfigForm, positioned before "Speichern", sharing the disabled-during-either-request semantics with the DKV Fleet InboxConfigForm it mirrors. Shows a waiting label, then a green success line or a red line with the server's literal error text; any form-field change clears the previous result.
  • Four new i18n keys (testConnection, testTesting, testSuccess, testFailed) added under tenderRadar.emailAlerts in both de.json and en.json, wording taken verbatim from dkvFleet.form's existing four keys.
  • The component's doc comment, which previously stated no test-connection endpoint exists for this form, was rewritten to describe the button that now exists — only the D-15 rationale for the absent interval field survived unchanged.

Task Commits

Each task was committed atomically:

  1. Task 1: Endpunkt POST email-config/test — vom Formularrumpf bis zum Mailserver - 3bf550b (feat)
  2. Task 2: Knopf "Verbindung testen" im Postfach-Formular samt Beschriftungen - c4db3b2 (feat)

Both tasks were tdd="true"; test cases were authored alongside the implementation in the same commit per this plan's task-scoping (no separate RED/GREEN split was required by the plan).

Files Created/Modified

  • apps/api/src/tenders/tender-email-config.service.ts - added testConnection(userId, dto), optional ImapProvider/ExchangeInboxProvider constructor params, a service-level Logger
  • apps/api/src/tenders/tenders.controller.ts - added POST email-config/test handler (testEmailConnection) directly after saveEmailConfig, above @Get(':id')
  • apps/api/src/tenders/tender-email-config.service.spec.ts - 3 new cases (typed password passthrough, stored-credential fallback, protocol→provider selection)
  • apps/api/src/tenders/tenders.controller.spec.ts - makeFakeEmailConfigService gained testConnection; 1 new IDOR test; declaration-order guard extended
  • apps/web/src/lib/tender-radar-api.ts - added testEmailConnection(payload)
  • apps/web/src/app/(portal)/modules/tender-radar/settings/components/EmailAlertConfigForm.tsx - test button, isTesting/testResult state, handleTestConnection, feedback rendering, corrected doc comment
  • apps/web/src/app/(portal)/modules/tender-radar/settings/components/EmailAlertConfigForm.test.tsx - mock factory extended with testEmailConnection, next-intl mock gained params interpolation + 4 new keys, 2 new test cases
  • apps/web/src/app/(portal)/modules/tender-radar/my-sources/my-sources.test.tsx - mock factory and translation table extended so component import doesn't throw (no new test cases required by the plan)
  • apps/web/src/messages/de.json / apps/web/src/messages/en.json - 4 new keys each under tenderRadar.emailAlerts

Decisions Made

  • testConnection backfills username AND password independently, unlike saveConfig's credChanged gate which only ever needs to fill in the one field the caller left out on a partial re-save. A connection test can arrive with a fully blank form (test right after loading a saved config), so both fields need their own fallback.
  • Used NestJS Logger (matching every other service in apps/api/src/tenders/) instead of console.error for the credential-decrypt failure path, consistent with codebase convention rather than the DKV analog's inline this.logger.
  • Route-order comment states the accurate mechanism (NestJS resolves per HTTP verb; a GET placeholder cannot shadow a POST route today) instead of the "sonst 404" phrasing the plan explicitly flagged as false — per the plan-check trap warning.

Deviations from Plan

None - plan executed exactly as written, including the three traps called out in execution notes (mock-factory export gap, stale doc-comment, route-order comment accuracy).

Issues Encountered

None.

User Setup Required

None - no external service configuration required. The browser UAT in Task 2's human-check block (real IMAP/EWS mailbox test) requires a Docker rebuild/restart, which is explicitly the user's responsibility per this repository's conventions (Kein Docker-Deploy auf Testserver) — it runs at phase end, not during this execution.

Next Phase Readiness

  • Backend and frontend automated verification green: API 646/646 tests (up from a 60-test baseline in the two touched spec files, now 64), typecheck clean; Web 228/228 tests (touched files: 5→7 in EmailAlertConfigForm.test.tsx), typecheck clean, locale-key check passes for both languages.
  • Plan-level commit ledger: plan_head_before: 5da58ad1827e86ea26cbe89e120a3a6cbcbe4f7f, commits: 2 (measured via git rev-list --count).
  • Outstanding: the browser UAT itself (Task 2's human-check block) is not yet run — it needs a real mailbox and the user's own Docker rebuild, and per human_verify_mode = end-of-phase is expected to happen at phase close, not mid-execution. WINDOWS #16 stays open until that UAT is confirmed.
