Every popup is now called *Popup instead of *Window in its file, root node,
node name, class and variable, and PopupWindow becomes BasePopup. Player is
PlayerRow, SongListObject is SongRow and Character is CharacterCard. Script
files are snake_case and scene files PascalCase, each matching its class or
root node, and LightGrayTheme.tres is light_gray_theme.tres.
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/
