Antigravity Builds an App, Kane CLI Tests It — Zero Code

Antigravity × Kane CLI — in this video you'll learn how to have Google's Antigravity agent build a web app from a screenshot and then test it end to end with Kane CLI, without writing a single line of test code. Kane CLI runs natural-language browser and API tests from your terminal and saves them to KaneAI, TestMu AI's AI-native test agent. In this video you will learn: • How to prompt Antigravity to build an Amazon-style storefront from a screenshot and serve it locally • How to hand Antigravity the Kane CLI agents.md so it knows how to author and run tests on its own • How Antigravity writes a test suite in Markdown and runs it with kane-cli testmd run --agent --headless in the background • How to read the step-by-step results — carousel, product modal, add to cart, location selector, search and filter, all passed • How the same run lands in KaneAI as a saved test case you can re-run, share, and inspect Demo: Amazon clone built by Antigravity (Gemini 3.5 Flash), tested by Kane CLI — every step passed, results in Result.md and the KaneAI dashboard. #KaneCLI #Antigravity #AITesting #TestAutomation #TestMuAI
