7 critical user journey tests for frontend deployment with AI assistance

AI coding tools can quickly generate working websites, but a few manual clicks don't prove real users can complete tasks. Before going live, you must test these 7 complete journeys from end to end: initial load, login/registration, core features, form submission, file upload, navigation routing, and permission sessions.

Key points

Test initial screen and loading: Check desktop and mobile layouts, usability after refresh, and ensure there are no blank screens or console errors.
Test registration and login: Verify required form fields, invalid credential prompts, post-registration redirection, and whether the session persists after a refresh.
Test core features: Check interception of missing inputs, loading/progress states, failure messages, and prevention of duplicate click submissions.
Test forms and files: Verify special characters, character limits, retention of filled data upon failure, file size and type restrictions, and drag-and-drop or click-to-upload functionality.
Test permissions and sessions: Check redirection for unauthenticated users accessing protected pages, restrictions on unauthorized access, and whether protected content remains inaccessible after logout.

Pitfalls

The core action button was double-clicked and submitted twice, resulting in duplicate records.
Users were still able to access content requiring account permissions after logging out.

- Test all user journeys from start to finish before launching (First visit, Sign-up/login, Core feature, Form submission, File upload, Navigation, Permissions).
- Prevent duplicate submissions on buttons (e.g., disable on submit or handle double-clicks).
- Ensure proper validation, error messages, and loading/progress states for all forms and tasks.
- Verify session persistence and access control for protected routes.

Copy-ready prompt

Please write or refine the frontend code for [Page/Feature Name] and ensure it passes the following tests: 1. Initial screen and mobile layout render correctly and remain usable after a page refresh; 2. Forms and core features include complete input validation, error prompts, and loading/progress states; 3. Prevent duplicate submissions caused by double-clicking buttons; 4. Implement proper access control and route redirection. Please check the code for any uncaught errors or vulnerabilities.
