Your Vibe-Coded App Isn’t Production-Ready — Until You Smoke Test It [PAID]

Shipping an AI-built app that works on your machine but breaks for real users? You’re not alone. Here’s a 3-phase, 12-test smoke testing system that catches the bugs unit tests miss — mobile layout failures, production environment mismatches, data edge cases, and the silent authentication breaks that only appear after deployment. No coding required, just a browser, a phone, and 30–60 minutes.

Have you ever launched an app and watched it break in ways you never imagined?

I have, more times than I can count.

My first app, an AI image search tool, only worked on my computer. I had to kill it a year later.

App #2 reached hundreds of users before crashing in production. App #3 broke just before I announced it, caught it in time, barely. Apps 4, 5, and 6? Each found new ways to fail.

Here’s what surprised me: none of them failed because I skipped unit tests.

They failed because I hadn’t systematically walked through what real users would do. I didn’t test flows on real devices. I didn’t try to break things. I trusted code that “worked” in isolation, without verifying that the entire system held up in the wild.

AI made it easy to ship features. Whether you’re using Claude Code, Cursor, or any other tool, the code comes fast. But I had no way to know if what I shipped actually worked.

What you’ll go through with me:

• What is smoke testing — and why unit tests won’t save you
• The Three-Phase System — the complete testing framework
• Phase 1: Pre-Deployment Testing — 6 tests before launch
• Phase 2: Post-Deployment Testing — 3 tests before announcing
• Phase 3: Feature Update Testing — the ongoing testing loop
• Testing Mindset & When to Ship — decision frameworks for confident launches
