unity-testability

Move rules and algorithms that do not need Transform, GameObject, or scene state into plain C# classes, then call them from a thin MonoBehaviour. Inject configuration through parameters instead of reading static globals so tests can supply their own values.

EditMode tests run in the editor without entering play mode and suit pure C# logic. PlayMode tests run in a live scene and are needed when behavior depends on GameObjects, physics, or runtime scene state.

Keep logic Unity-facing when it is tiny and tightly bound to scene objects, lifecycle callbacks, or engine APIs. Forcing test seams everywhere adds abstraction without benefit; prefer a few meaningful seams over abstraction for its own sake.

Pass configuration and dependencies into classes through constructors or method parameters instead of reading static globals. This lets EditMode tests supply controlled values and removes hidden coupling to global state.

No, it is documentation-only guidance with no scripts or REST operations. It loads freely under any operating mode and only produces review questions, refactoring suggestions, and candidate test lists.
