Build an AI QA Agent for Expo Apps with EAS Workflows in minutes today

Michał Pierzchała outlines a method for building a lightweight mobile QA agent for Expo apps using EAS Workflows and the agent-device tool, designed to automate UI verification for iOS and Android pull requests without requiring a large test framework. The approach leverages EAS Workflows' capabilities to handle mobile-specific continuous integration tasks, such as reusing builds and running custom jobs, to streamline the QA process. By utilizing a minimal template, developers can quickly set up a QA agent that inspects UI changes, takes screenshots, and posts a QA summary directly under pull requests on GitHub. The strategy emphasizes a split between deterministic tasks, like installing and launching apps, and variable, agent-driven tasks, such as UI inspection and reporting, to maintain reliability and flexibility. This setup enables fast iteration and scalability, allowing teams to expand coverage as needed while keeping the agent small and efficient.
