What problem does it solve? Setting up end-to-end tests for a game project requires building test fixtures, scenario builders, input simulators, and async assertion utilities from scratch, which is error-prone and often produces brittle tests. This Skill scaffolds that entire foundation automatically, tailored to the detected game engine and architecture. ## Core Features & Use Cases - Engine Detection and Tailored Generation: Detects Unity, Unreal, or Godot projects and generates engine-appropriate infrastructure such as GameE2ETestFixture, ScenarioBuilder, InputSimulator, and AsyncAssert. - Domain-Aware Scenario Builders: Analyzes the game's state manager, input system, and domain entities to generate fluent scenario configuration APIs with project-specific methods. - Working Example Test and Documentation: Produces a runnable example E2E test plus a README covering quick start, best practices, and troubleshooting. - Use Case: A Unity developer with an initialized test framework runs the workflow to get a complete Tests/PlayMode/E2E directory with assembly definitions, base fixtures, and a passing infrastructure verification test. ## Quick Start Ask the assistant to set up e2e testing infrastructure for your game project and provide your game state manager class and main gameplay scene name.
