What problem does it solve? Setting up end-to-end testing for a game project requires building test fixtures, scenario builders, input simulators, and async assertion utilities from scratch, which is error-prone and often skipped entirely. This Skill scaffolds that entire foundation automatically, tailored to the project's engine and architecture. ## Core Features & Use Cases - Engine Detection and Analysis: Detects Unity, Unreal, or Godot projects and identifies the game state manager, input system, and main gameplay scene before generating any code. - Infrastructure Generation: Creates a test fixture base class, fluent ScenarioBuilder, InputSimulator, and AsyncAssert utilities matched to the detected engine and input system. - Working Example Test: Produces a runnable example E2E test plus a README with quick start, best practices, and troubleshooting guidance. - Use Case: A Unity developer with an existing game wants to start writing E2E tests. The Skill generates the Tests/PlayMode/E2E directory with an assembly definition, fixture, and utilities, then verifies setup with a passing infrastructure test. ## Quick Start Ask the assistant to scaffold e2e testing infrastructure for your game project and provide your game state class and main scene name.
