// NOTE on coverage scope:
|
|
// `PlayQueueLauncher` is almost entirely network/UI glue:
|
|
// - every public method calls into [PlexClient.createPlayQueue] or
|
|
// [PlexClient.createShowPlayQueue] (network),
|
|
// - then setups [PlaybackStateProvider] (Provider),
|
|
// - then calls [navigateToVideoPlayer] (Navigator + DownloadProvider +
|
|
// SettingsService singleton + Provider).
|
|
//
|
|
// Without re-implementing that entire dependency tree, the meaningful
|
|
// unit-testable surface is:
|
|
// - `PlayQueueError` preserves the underlying failure.
|
|
// - `launchShuffledShow` short-circuits BEFORE any network call when the
|
|
// metadata is not a show or season — that's a pure pre-flight branch.
|
|
// - `launchFromCollectionOrPlaylist` short-circuits when the input is
|
|
// neither a `PlexMetadata` nor a `PlexPlaylist`.
|
|
//
|
|
// Everything else (success/empty-queue/error paths) requires a full
|
|
// PlexClient fake + a Provider tree + a real Navigator. Skipped.
