Phaser Unit Testing Patterns

"Test Phaser game objects without a running game instance."

When to Use This Skill

Use when creating unit tests for:

• Phaser game objects (Birds, Pigs, Blocks, etc.)
• Matter.js physics bodies
• Game systems that depend on Phaser Scene
• Event-driven game logic

CRITICAL LESSON FROM BUG-011: Never use real Phaser Scene instances in unit tests. They require a running Phaser Game instance and will fail with errors like "scene.init is not a function". Always use MockScene pattern.
