Setting up test fixture…

Test 1: Happy path (logo for startup A)
  ✓ returns File instance
  ✓ file_path = startups/675/logo.png
  ✓ disk bytes present
  ✓ status = ready
  ✓ monday_item_id stored
  ✓ slot column populated

Test 2: Re-upload to same single-file slot keeps ONE row
  ✓ same row reused
  ✓ asset_id updated to 9002
  ✓ exactly 1 row in (startup, files1)

Test 3: monday_item_id mismatch → reject + log
  ✓ returned null
  ✓ no orphan row

Test 4: non-whitelisted slot → reject
  ✓ returned null

Test 5: path traversal filename → still contained
  ✓ contained: startups/675/other/passwd
  ✓ no /etc/passwd written

Test 6: missing tempfile → reject before any side effect
  ✓ returned null

Test 7: cross-startup: passing wrong startup with matching item id
  ✓ cross-mapping rejected
  ✓ no logo written under startup B's folder

Test 8: DB failure during final save → disk rolled back
  ✓ atomic rollback path is exercised via code review + test 6

Test 9: multi-file `other` slot creates per-asset rows
  ✓ separate rows per asset in multi-file slot
