Replace a hopeful shrug with evidence your app works — without reading a line of code.
Does It Actually Work? — Test the App You Built With AI Without Reading the Code
You built an app by talking to an AI, and it works when you drive it — but a quiet question keeps stopping your hand: how would you even know if it's broken? This 24-page field guide walks you up the evidence ladder without reading a line of code — cold-user test, deliberate abuse, the states your app has never lived in, tests you can own — and hands you a one-page smoke check to run in ten minutes before every share. One boundary is held throughout: this book verifies; it does not fix.

What's inside
- The Happy-Path Problem: why an app works thirty times for you and dies in a stranger's first minute — and why AI-built code sits on the happy path unevenly, in ways you cannot see by looking
- Drive It Like a Stranger: the cold-user test run properly — one real person, one written mission, the discipline of saying nothing, a four-column sheet of what to record, and a Blocked/Confused/Annoyed triage that decides what happens next
- Break It on Purpose: a catalog of cheap sabotage you run against your own app — empty and junk input, café/O'Brien/emoji, double-clicks, mid-action refresh, two tabs at once, midnight and month boundaries, keyboard-only — each with what to expect and the exact red flag to log
- The States You Forgot: day one with no data, empty-again after use, a mountain of data, a throttled connection, honest offline failure, and someone else's device
- Tests You Can Own: how to ask your assistant for automated checks you can't read — and the "see it fail first" ritual that turns a wall of green from decoration into evidence, plus the one red flag (a test quietly changed to pass)
- The Coverage Mirage: why a high coverage number can prove almost nothing, the proofreader who "read every page," and the one question to ask instead of "what's the coverage?"
- What You Still Can't Verify: the honest limits — security, crowds, data over time, maintainability, correctness between the points you sampled — and when to stop and pay a professional
- The Smoke Checklist: the whole book compressed to one page you rerun in ten minutes before every share, first stranger or hundredth update
- A plain-language glossary of every term, and an honest note on how the book was made
Who it's for
- Non-coders who built something with AI and hesitate to send anyone the link
- Anyone who wants evidence their app works before strangers touch it
Who it's not for
- Anyone expecting the book to fix what the checks find — it verifies, then hands clean findings to your assistant afterwards
- Anyone needing security, load, or professional-grade assurance — the book states those limits plainly and says when to pay a professional
Uses the browser you already have and the AI assistant you already build with — nothing new to buy, and no named tool required. The browser developer-tools labels it leans on were last reviewed July 2026; where a label has moved, the book tells you what to look for instead of the exact words. No statistics, user counts, or customer stories appear anywhere. Passing every check is evidence, not proof your app is correct — the book states that ceiling plainly.
Guidance, not gospel — this is a practical organisation tool, not legal, tax, medical, or religious authority.
