Trigger Error Responses
Common Error Handling Patterns
4xx Client Errors
- • Display user-friendly error messages
- • Highlight invalid form fields
- • Redirect to login on 401
5xx Server Errors
- • Show generic "try again" message
- • Log error details for debugging
- • Implement retry with backoff
Automation Tips
- • Status Code Assertions: response.status_code == 404
- • Error Message Validation: Assert error message matches expected format
- • UI Error Display: Verify error toast/alert appears on failure
- • Network Mocking: Use Playwright/Cypress route interception to force errors
