timer-testing-patterns
Efficient patterns for testing time-based game features, including timer manipulation and countdown verification. Use when testing timer functionality, countdown features, or time-based game mechanics. Never wait for natural countdown - use test seam setTimer() commands instead.

# Timer Testing Patterns
## Overview
Efficiently test timer functionality without waiting for natural countdown. Use test seam commands to manipulate timers directly.
## Timer Manipulation
**Use test seam commands**:
- `setTimer(seconds)` - Set timer to specific value
- `fastForwardTimer(seconds)` - Decrease timer by specified amount
- `triggerGameOver()` - Force game over condition
See `references/timer-commands.md` for detailed command usage.
## Testing Workflow
1. Use test seam to set timer to low value (e.g., 3 seconds)
2. Start game
3. Wait for timer to expire
4. Verify game over/level complete behavior
5. Test boundary conditions (9, 10, 11 seconds for color changes)
## Avoid Natural Countdown
**Never wait for natural countdown** (e.g., 60 seconds)
**Always use timer manipulation** for testing:
- Set timer to low value for quick testing
- Test boundary conditions efficiently
- Verify both positive (timer works) and negative (timer expires) cases
## Test Seam Implementation
See `references/test-seam-implementation.md` for code examples of adding timer commands to test seam.
