Quick answer

How to test an AI-generated app before launch

AI-generated code fails in a particular way: it usually compiles, often looks plausible, and breaks exactly where nobody looked — a route that never renders, a form that submits nowhere, a blank screen behind a green build.

That is why testing the source is not enough. The checks that matter run against the rendered app: the pixels and flows your users will actually meet.

  1. 1

    Run it, don’t read it

    Reading generated code catches style problems, not launch problems. Load the app in a real preview and click the primary flow end to end before judging anything else.

  2. 2

    Check the rendered result

    PromptUI’s verification runs against the rendered app: does the page paint, is the content visible, do key elements exist. Findings are reviewable, not a silent score.

  3. 3

    Fix findings where they were found

    Describe each fix in plain language and confirm it in the same preview that flagged it — the loop stays honest because the check and the fix look at the same surface.

  4. 4

    Deploy, then re-check the live URL

    A preview passing is not the finish line. Deploy and confirm the live URL behaves the same — PromptUI keeps the deployment and its checks in one place.

  5. 5

    Keep the proof

    PromptUI records the checks each build passed on a proof page you can share, so “tested” is inspectable later — by you, a client, or a teammate.

Bring your app to PromptUI

Import the repository, watch the verification run on the real rendered app, and go from repo to launched.

Common questions

Is this the same as unit testing?
No — unit tests exercise functions; this verifies the rendered app a user meets. Both have value; for AI-generated apps the rendered check catches the failures that matter at launch.
What if my app was built in another tool?
Push it to GitHub and import it into PromptUI. The verification, deploy, and launch steps work the same on imported projects.
