TestMu AI Expands Kane CLI with DevTools Assertions for Deeper Browser Validation
Event summary
- TestMu AI introduced DevTools Assertions in its Kane CLI on June 16, 2026, enabling natural language-based validation of browser internals.
- The feature allows developers to validate network requests, API responses, console logs, cookies, local storage, and performance metrics.

This move aligns with the broader industry trend toward autonomous software verification and quality engineering workflows.
