Covers a cache size above 1: songs are preloaded until the setting is
reached, playing a song tops the cache up again, and the cache keeps
filling after a failed download once the server answers again.
MusicServerClient functions now take an optional on_failed callback,
called when a request fails or returns invalid JSON. Before, a failed
request was silently dropped, so a failure while preloading a song left
Playlist.is_song_downloading set forever and no more songs were fetched.
Song fetching retries the step that failed (download, queue or info)
every song_fetch_retry_seconds, so the server and the game keep the same
playlist.
The previous tests never compiled: they used GUT's assert functions,
Godot 3 APIs and reassigned autoload functions, so no test ran.
- 90 tests: unit tests for the playlist, songs, player scoring, time
formatting, search and the server client, plus integration tests
that run MainWindow and SyncWindow against a fake server
- Keybind tests check that Alt+<number> and Ctrl+Alt+<number> keep
following the player rows while players are added and removed
- run_tests.sh finds Godot and runs the suite headless (~10 seconds)
- CI runs the tests before the build job in gitea-build.yaml; the
separate test.yml used a GitHub action that does not exist
- GdUnit4 is committed instead of ignored, since the project enables
it, and .gitea/ is no longer ignored
- Exported builds leave out tests/ and addons/gdUnit4/
