🔁 Automate interactive Flutter tests with marionette_mcp! LeanCode’s Mateusz Wojtczak 💙 dives into the open-source tool that gives AI coding agents "eyes and hands" to interactively test Flutter apps.

@matiwojt Direct widget-tree access should make UI tests much less brittle than screenshots. I would also keep a few end-to-end smoke flows for the real device.

@matiwojt marionette_mcp 这名字挺直白。 给 AI coding agent 加「眼和手」，去做交互式 Flutter 测试。 开源工具链入口，别当成又发了一个大模型。

@matiwojt agents driving flutter tests is where it gets interesting. marionette_mcp gives claude code hands on the widget tree which beats screenshot diffing. i run a couple test agents at once and ended up putting them on one canvas in 49agents so i stop tab hopping between them.

Thanks for having me! 💙

@matiwojt Interactive testing is the missing layer for coding agents. A green build can still hide broken flows, so giving agents eyes and hands seems useful if the test steps stay reviewable.

@matiwojt letting agents tap through the app themselves beats guessing from screenshots. most of my broken tests got fixed once the agent could just see what actually happened.
