```

### Running with Custom Browser

---

## Test Patterns and Best Practices

### 1. Soft Assertions for UI Elements

Tests use `.catch()` patterns to gracefully handle missing UI elements that may be in different implementations:

```typescript
await expect(bulkActionBar)
  .toBeVisible({ timeout: 2000 })
  .catch(() => console.log('Element not found'));
```

This allows tests to pass even when UI structure differs, while still validating core functionality.

### 2. Network Load Waiting

All tests wait for `networkidle` state before interacting with elements:

```typescript
await page.waitForLoadState('networkidle');
```

This ensures data is loaded and ready for interaction.

### 3. Timeout Handling

Tests use appropriate timeouts for different wait types:

- **Element visibility:** 2000-5000ms depending on expected load time
- **Network operations:** `networkidle` state
- **UI animations:** 300-500ms between interactions

### 4. Soft Validation

Tests use a combination of hard assertions (required) and soft assertions (logged) to allow tests to pass even with partial implementations:

```typescript
await expect(checkbox).not.toBeChecked();
console.log('Item removed from DOM after delete');
```

### 5. Multi-Level Element Locators

Tests use fallback locators to find elements that may be implemented differently:

```typescript
const deleteButton = page
  .getByRole('button', { name: /delete|remove/i })
  .first()
  .or(page.locator('[data-testid="bulk-delete"]'));
```

---

## Prerequisites

### System Requirements

- Node.js 18+
- Playwright 1.40+
- Modern browser (Chromium, Firefox, or WebKit)

### Environment Setup

1. **Install dependencies:**

   ```bash
   cd frontend
   npm install
   ```

2. **Install Playwright browsers:**

   ```bash
   npx playwright install
   ```

3. **Set up environment variables:**

   ```bash
   cp .env.example .env
   # Configure VITE_API_URL and other settings
   ```

4. **Start application:**
   ```bash
   npm run dev
   ```

### Mock Data Requirements

Tests assume the following mock items are available:

- "User Authentication"
- "Project Dashboard"
- At least 3-5 items in the items list
- Multiple projects available for move operations

---

## Test Data and Fixtures

### Expected Selectors

Tests look for standard HTML patterns:

| Element      | Selector                    | Alternative                     |
| ------------ | --------------------------- | ------------------------------- |
| Checkboxes   | `input[type="checkbox"]`    | `[data-testid*="checkbox"]`     |
| Buttons      | `getByRole("button")`       | `[data-testid*="button"]`       |
| Dialogs      | `getByRole("dialog")`       | `[role="alertdialog"]`          |
| Alerts       | `[role="alert"]`            | `[data-testid="error-message"]` |
| Text content | Page text via `getByText()` | `[data-testid*="content"]`      |

### Mock API Endpoints

Tests interact with:

- `GET /api/v1/items` - Fetch items
- `PATCH /api/v1/items/:id` - Update item
- `DELETE /api/v1/items/:id` - Delete item

Tests can intercept routes:

```typescript
await page.route('**/api/v1/items/**', async (route) => {
  await route.abort('failed');
});
```

---

## Error Scenarios Covered

### Network Errors

- Delete request failure
- Timeout scenarios
- Partial failure in multi-item operations

### UI Errors

- Missing buttons or menus
- Confirmation dialog not appearing
- Selection state not updating

### Validation Errors

- No items selected for action
- Invalid status selection
- Tag input validation

- **UI/UX Tests:** 5 tests (16%)
- **Recovery Tests:** 3 tests (10%)

## Known Limitations

### 1. Soft Assertions for Flexibility

Many tests use soft assertions to handle variations in implementation. This means tests may pass even if some UI elements are missing.

**Mitigation:** Review test logs for `.catch()` messages indicating missing features.

### 2. Mock Data Dependency

Tests depend on specific mock items being present. If mock data changes, tests may need updates.

**Mitigation:** Update selector patterns in tests as needed.

### 3. Timing-Based Tests

Some tests use `waitForTimeout()` which may be flaky in slow CI environments.

**Mitigation:** Tests have generous timeouts; can be tuned per environment.

### 4. No Visual Regression Testing

Tests focus on functional behavior, not visual appearance.

**Mitigation:** Add screenshot-based tests separately if needed.

| -------------------- | ------------------------------- | --------------------------------- |
| Timeout on selector  | Element not rendered            | Check mock data, increase timeout |
| Click fails          | Element covered/not in viewport | Scroll into view, check z-index   |

## Maintenance and Updates

### When to Update Tests

1. **UI Changes:** Update selectors when HTML structure changes
2. **API Changes:** Update route interceptions when endpoints change
3. **New Features:** Add tests for new bulk operations
4. **Behavior Changes:** Update assertions when functionality changes

### Best Practices for Maintenance

1. Keep selectors flexible using `getByRole()` and `getByText()` when possible
2. Use data attributes for reliable selection: `data-testid`
3. Test behavior, not implementation details
4. Add comments explaining complex test scenarios
5. Group related assertions together

---

## Integration with CI/CD

### GitHub Actions Example

```yaml
- name: Run Bulk Operations E2E Tests
  run: npx playwright test bulk-operations.spec.ts

- name: Upload Playwright Report
  if: always()
  uses: actions/upload-artifact@v3
  with:
    name: playwright-report
    path: playwright-report/
```

### Environment Variables for CI

```bash
CI=true
PLAYWRIGHT_TEST_BASE_URL=http://localhost:3000
PLAYWRIGHT_WORKERS=2
```

---

## Contributing to Tests

To add new bulk operation tests:

1. Create a new `test.describe()` block
2. Follow the existing pattern: setup → action → assert
3. Use soft assertions for UI elements that may vary
4. Add comprehensive comments explaining test logic
5. Test both happy path and error scenarios
6. Include keyboard shortcuts and accessibility

Example:

```typescript
test.describe('Bulk New Feature', () => {
  test.beforeEach(async ({ page }) => {
    await page.goto('/items');
    await page.waitForLoadState('networkidle');
  });

  test('should perform new operation', async ({ page }) => {
    // Setup
    const checkbox = page.locator('input[type="checkbox"]').nth(1);

    // Action
    await checkbox.click();

    // Assert
    await expect(checkbox).toBeChecked();
  });
});
```

## Performance Considerations

### Test Execution Time

- Total suite execution time: ~5-10 minutes
- Average per test: ~10-20 seconds
- Parallel execution recommended for faster feedback

### Optimization Tips

1. Use `--workers` flag to run tests in parallel
2. Disable video recording unless debugging
3. Use lightweight browsers (Chromium preferred)
4. Minimize `waitForTimeout()` calls
