# Test Suite Summary

## Test Organization

All tests are now organized in `/tests/mjs/` with numbered prefixes for execution order.

### Available Tests

| Test File | Purpose | Status |
|-----------|---------|--------|
| `0-zoom.test.mjs` | Zoom control functionality | ✅ Ready |
| `1-toggles.test.mjs` | Comprehensive toggle testing with real-time verification | ✅ Ready |

## Test Improvements

### 1-toggles.test.mjs Enhancements

**Key Features Added**:
1. ✅ **Real-time visual verification** - Tests verify DOM updates happen immediately without refresh
2. ✅ **Screenshot capture** - Takes before/after screenshots for icon toggle
3. ✅ **localStorage validation** - Verifies state persistence
4. ✅ **Synchronization testing** - Ensures action bar and menu toggles stay in sync
5. ✅ **Detailed reporting** - Clear pass/fail for each test with explanations

**Tests Performed**:
- Length Toggle (Action Bar)
- Icon Toggle (Action Bar) - **with screenshot verification**
- Theme Toggle (Action Bar)
- Length Toggle (Menu + Sync)
- Icon Toggle (Menu + Sync) - **with real-time rendering check**
- Theme Toggle (Menu + Sync)

**Critical Addition**: Tests explicitly check if visual changes happen without page refresh (the bug reported by user)

## Running Tests

```bash
# Individual test
bun tests/mjs/0-zoom.test.mjs
bun tests/mjs/1-toggles.test.mjs

# All tests in order
for test in tests/mjs/*.test.mjs; do bun "$test"; done
```

## Test Output

Each test provides:
- Clear ✅/❌ indicators
- Before/after state comparison
- localStorage verification
- Console error detection
- Summary with total pass/fail count

## Screenshots

Toggle test saves screenshots to `tests/screenshots/`:
- `before-icon-toggle.png`
- `after-icon-toggle.png`

Use these to visually verify rendering happens without refresh.

## Notes

- Server must be running on http://localhost:1999
- Tests run in headed mode (browser visible) for manual verification
- Press Ctrl+C to exit after reviewing results
- All tests are executable (`chmod +x` already applied)

## Next Steps

Additional tests to add:
- Keyboard shortcuts test (L, I, V keys)
- Hamburger menu animation test
- Print/PDF button tests
- Responsive design tests
