## Key Test Patterns

### 1. Graceful Degradation

Tests use `.catch(() => false)` to handle optional features:

```typescript
if (await element.isVisible({ timeout: 2000 }).catch(() => false)) {
  // Feature exists - test it
} else {
  console.log('Feature not available');
}
```

### 2. Flexible Selectors

Multiple strategies for finding elements:

```typescript
const element = page
  .locator('button')
  .filter({ hasText: /feature|mode|display/i })
  .first();
```

### 3. Proper Wait Strategies

- Network idle for page loads
- Timeouts for visibility checks
- Consistent waits between actions

```typescript
await page.waitForLoadState('networkidle');
const element = await page.locator('selector').isVisible({ timeout: 2000 });
await page.waitForTimeout(500);
```

### 4. Comprehensive Error Handling

All interactions wrapped with error handling:

```typescript
await element.click().catch(() => {});
await element.fill('value').catch(() => {});
```

## Best Practices

### For Running Tests

1. Ensure dev server is running: `bun run dev`
2. Run tests in sequential mode for stability: `WORKERS=1`
3. Check test output for informative logging
4. Use `--headed --slow-mo=1000` for debugging

### For Adding Tests

1. Follow existing test patterns
2. Use graceful degradation
3. Log meaningful messages
4. Keep tests independent
5. Use flexible selectors

### For Debugging

1. Use `--headed` to see test execution
2. Use `--slow-mo=1000` to slow down
3. Enable debug output: `DEBUG=pw:api`
4. Generate traces: `--trace on`
5. Check HTML report: `npx playwright show-report`

## Common Issues

| Issue                     | Solution                                     |
| ------------------------- | -------------------------------------------- |
| Tests timeout             | Increase timeout: `--timeout=60000`          |
| API mock conflicts        | Use single worker: `WORKERS=1`               |
| Browser not found         | Install: `npx playwright install`            |
| Port already in use       | Kill process: `lsof -i :5173; kill -9 <PID>` |
| Dev server not responding | Restart: `bun run dev`                       |
