# Testing — Playlist Butler

## Install
- Chrome → `chrome://extensions` → Developer mode → Load unpacked → select `playlist-butler/`

## Smoke
1) Open a playlist page on YouTube (logged in).
2) Popup → Index list
3) Ensure videos appear in list; paging works; export works.

## Continuation tests (Mission 001)
### Test A: Watch Later (WL)
- Go to `https://www.youtube.com/playlist?list=WL`
- Index list
- Expect Debug:
  - `initial continuation token found`
  - multiple `continuation fetch ok`
  - multiple `continuation parsed { items: >0, nextToken: true }`
- Expect UI total count > 100 and continues rising.

### Test B: Large regular playlist
- `https://www.youtube.com/playlist?list=<ID>`
- Repeat above.

## Regression
- Reindex works.
- Page size switch (25/50/100) works.
- Back-to-top appears when bottom pager visible.
