verify-scanner

name	verify-scanner
description	Run scanner and library-scan tests after changes to file parsing, scan orchestration, or fixture media. Use when modifying scanner.py, library_scan.py, genre_tags.py, or backend/tests/fixtures/media/.

Verify scanner changes

When to use

After changes to:

• backend/app/scanner.py — filename parsing, show/movie detection
• backend/app/library_scan.py — scan orchestration, DB population
• backend/app/genre_tags.py — genre normalization
• backend/tests/fixtures/media/ — test media layout

Steps

1. Run API tests (scanner tests live in the api layer):

   .\scripts\test.ps1 -Layer api
   

2. Focus on scanner tests for faster iteration:

   cd backend
   $env:APP_ENV="test"; $env:TEST_MODE="true"
   .\.venv\Scripts\pytest tests/test_scanner.py -q
   

3. For manual smoke against fixture media:

   cd backend
   python scripts/smoke_scan.py
   

4. Fix failures; re-run until green, then run full api layer

Test file map

File	Covers
test_scanner.py	scan_library, episode parsing, supplemental content, fixture media
test_library_api.py	browse/movies/shows after scan (indirect scanner coverage)

Self-correction loop

run test_scanner.py → read traceback → fix scanner/library_scan → re-run → smoke_scan.py → full api layer

Notes

• Tests use fixture media in backend/tests/fixtures/media/; never scan the developer's real MEDIA_ROOTS
• Import app.db as db and use db.engine in tests after overrides
• SCAN_LIMIT in config can cap files during dev scans; tests use isolated DB via tmp_path
