console.log('🎯 Key Test Scenarios:');
console.log('');

console.log('Scenario 1: Basic Movement');
console.log('- Press → arrow: Snake moves right, extends to (1,0)');
console.log('- Press ↓ arrow: Snake moves down, extends to (1,1)');
console.log('- Press ← arrow: Snake moves left, extends to (0,1)');
console.log('- Press ↑ arrow: Snake moves up, extends to (0,0)');
console.log('');

console.log('Scenario 2: Letter Collection');
console.log('- Snake moves to letter cell');
console.log('- Snake stops automatically');
console.log('- Letter is collected and marked');
console.log('- Snake grows with colored segment');
console.log('- Movement resumes');
console.log('');

console.log('Scenario 3: Visual Feedback');
console.log('- Correct letters: Snake segment turns green');
console.log('- Wrong letters: Snake segment turns red');
console.log('- Board letters: Change to collected state');
console.log('- Animations: Growth, movement, and theme effects');
console.log('');

console.log('Scenario 4: Edge Cases');
console.log('- Boundary collision: Snake stops at grid edge');
console.log('- Self collision: Prevents moving into snake body');
console.log('- Rapid input: Handles multiple quick key presses');
console.log('- Theme changes: Updates colors dynamically');
console.log('');

console.log('✨ Expected Visual Behavior:');
console.log('');
console.log('When arrow keys are pressed:');
console.log('1. Snake head immediately shows direction arrow (▶ ▼ ◀ ▲)');
console.log('2. Snake extends in the movement direction');
console.log('3. If letter is collected:');
console.log('   - Letter cell changes to "collected" state');
console.log('   - Snake grows with new colored segment');
console.log('   - Green for correct letters (✓)');
console.log('   - Red for wrong letters (✗)');
console.log('4. Movement animations play smoothly');
console.log('5. Theme colors apply to all visual elements');
console.log('');

console.log('🔧 Test Configuration:');
console.log('- Framework: Vitest + React Testing Library');
console.log('- Environment: jsdom for DOM simulation');
console.log('- Mocks: Animation frames, timers, performance');
console.log('- Coverage: Comprehensive movement and visual testing');
console.log('');
