To manually test user management functionalities:

1. 🔐 Login as Admin:
   - Go to /login
   - Use: admin / admin123
   - Verify you can access admin features

2. 👥 Access User Management:
   - Go to /users
   - Verify you see the user management page
   - Check that statistics are displayed correctly

3. ➕ Create New User:
   - Click "Add New User"
   - Fill in: Name, Email, Username, Password, Role
   - Submit and verify user appears in list

4. ✏️ Edit User:
   - Click dropdown next to any user (not yourself)
   - Select "Edit User"
   - Change name/email/role and save
   - Verify changes appear in users list

5. ⬆️ Promote User:
   - Find a staff user in the list
   - Click dropdown → "Promote to Admin"
   - Confirm the action
   - Verify user role changes to Admin

6. ⬇️ Demote User:
   - Find an admin user (not yourself)
   - Click dropdown → "Demote to Staff"
   - Confirm the action
   - Verify user role changes to Staff

7. 🚫 Deactivate User:
   - Find any user (not yourself)
   - Click dropdown → "Deactivate User"
   - Confirm the action
   - Verify user status changes to Inactive

8. ✅ Reactivate User:
   - Find an inactive user
   - Click dropdown → "Reactivate User"
   - Confirm the action
   - Verify user status changes to Active

9. 📦 Bulk Operations:
   - Click "Bulk Actions" button
   - Select multiple users with checkboxes
   - Try "Activate Selected" or "Deactivate Selected"
   - Verify changes are applied to all selected users

10. 🛡️ Admin Protection Tests:
    - Try to deactivate yourself (should fail with error)
    - Try to demote the last admin (should fail with error)
    - Verify these protections work as expected

🔍 What to Look For:
- Flash messages appear for success/error states
- Page redirects work correctly after actions
- User list updates to reflect changes
- Protection mechanisms prevent dangerous actions
- Statistics update correctly after changes
- Search and filtering work properly

If user management functions are not working, check:

1. 📂 File Updates:
   - Replace user management routes in app.py
   - Update users.html template
   - Ensure admin_required decorator is properly implemented

2. 🗄️ Database Check:
   - Verify users table exists
   - Check that admin user exists with correct role
   - Ensure foreign key relationships are set up

3. 🔧 Code Integration:
   - Add the enhanced routes to your app.py
   - Import required modules (datetime, etc.)
   - Ensure session management is working

4. 🎨 Template Updates:
   - Replace templates/users.html with enhanced version
   - Verify CSS variables are defined in style.css
   - Check JavaScript functions are loading

5. ⚙️ Configuration:
   - Ensure Flask app has proper secret key
   - Database connection is working
   - Session configuration is correct

6. 🧪 Testing:
   - Start with manual testing first
   - Check browser console for JavaScript errors
   - Verify network requests in browser dev tools
   - Check Flask console for Python errors

Common Issues & Solutions:
- 404 errors: Routes not properly registered
- 500 errors: Database connection or Python syntax issues
- Permission denied: admin_required decorator not working
- JavaScript errors: Check for missing functions in templates
- CSS issues: Verify CSS variables are defined
