# Headless Download Tests Run the full Rust suite: ```sh cd src-tauri cargo test --all-targets ``` Run the queue-manager harness when changing aria2 scheduling, concurrency, and retry behavior: ```sh cd src-tauri cargo test --test queue_manager -- --nocapture ``` Run the media metadata smoke test with an explicit URL when changing yt-dlp integration: ```sh cd src-tauri FIRELINK_LIVE_YOUTUBE_URL='https://www.youtube.com/watch?v=dQw4w9WgXcQ' \ cargo test filters_live_youtube_metadata_from_env --lib -- --ignored --nocapture ``` Run the real local Torrent runtime smoke test against the host bundled Aria2 binary. It starts a local tracker and two Aria2 daemons, then covers magnet metadata resolution, saved-metadata hash validation, selected-file output, pause/resume, ownership reporting, and cancel/remove: ```sh npm run smoke:torrent ``` Use `node scripts/smoke-torrent.js --binary /path/to/aria2c` when validating a packaged or target-specific Aria2 binary. Run the deterministic unavailable-tracker and Aria2-daemon-exit checks with: ```sh npm run smoke:torrent:failure-paths ```
