| Test Type | Example | |-----------|---------| | | Verify hasAccess() correctly denies private PDFs for anonymous users. | | Integration | Mock S3, request /download , ensure returned URL works and expires after the set time. | | Performance | Load‑test search + download for 10 k concurrent users; ensure <200 ms latency for signed‑URL generation. | | Security | Attempt to reuse an expired URL → expect 403 . | | Compliance | Run a script that scans metadata for missing license fields; fail build if any PDF lacks a license attribute. |
