We are entering the agentic era of E2E tests and agents interacting directly with Android emulators. Things are evolving quickly as we speak. Maestro MCP is a game changer in this matter 🔥

Hot take: the best UI test is the one you never had to write. Go through the flow yourself, record it, and you get something simple, deterministic, and much closer to how users actually interact with your product.

you just finished the feature. instead of tapping through 6 screens to get to it, ask the agent to go check it. the flow it just ran is your regression test.

Agentic UI testing is quickly becoming the new standard for writing mobile UI tests quickly. Easy to write, easy to maintain, targets the accessibility tree 🌳💯

I’ve been testing Maestro MCP these past few days and I’m genuinely impressed 🤯 After adding a feature to your app, ask Maestro to test the entire flow for you. It navigates the app and writes all the relevant tests 💯 This is NowInAndroid. Running via Claude desktop 👇

AUTOMATE mobile app testing with a flow your team can actually read, trust, and debug. build these flows in Maestro Studio, or let your coding agent write them through Maestro MCP.

Some developers are still hand-writing UI tests. The others let their coding agent do it with open-source Maestro MCP.

Had a great time last Friday in Dubai. Shared a small demo on using agent skills and @maestro__dev to turn a Jira story into automated tests, then send the evidence back to Jira. Slides:
