GAMESLASHGUT
By bitwes
Test GDScript in Godot with assertions, doubles and stubs, then rerun suites in the editor or CLI after gameplay changes.
Start: Install through Godot AssetLib, or put gut under addons, then enable it in Project Settings → Plugins.
Try: Create res://test/unit/test_example.gd extending GutTest, add a test_ function and assertion, configure the test directory and click Run All. Doubles and stubs isolate dependencies; the CLI can rerun the suite outside the editor.
Compatibility: The reviewed docs identify GUT 9.6.1 with Godot 4.6. GUT 9 targets Godot 4; GUT 7 requires Godot 3.4. Check the exact release rather than assuming all minor versions match.
