so I got nerd sniped by @o_kwasniewski with an experimental renderer being faster than agent-device in e2e, so now v0.21.29 comes with: β 2Γ faster Android taps and verified fills β 18Γ faster immediate screenshots, β 18% quicker on a 42-test suite enjoy
ok expo simulators are pretty cool. agent-device testing itself like it always does, now in the cloud
This is very cool and generally what we are seeing across our best apps. 99 of incident.io's last 144 mobile PRs were written by agents. Now the agents also run each change on an @expo cloud simulator with @agent_device and hand the reviewer screenshots and a video.
we ship nightlies now btw
Great article from @incident_io on testing apps in the cloud with agents. Nice insights and explanations on tunneling simulator access from a lightweight VM. Powered by @agent_device and @expo infrastructure!
we like this growth trajectory. latest drivers: T3 Code and e2e. happy to power great products with efficient agent verification tooling
agent-device just crossed 1M monthly downloads and 5k stars! π I have so much fun shipping this project to you, learning new things every day. hope you find it helpful
e2e by @TesterArmy runs mobile tests through our open-source @agent_device. Combine goal-based agent actions with exact assertions, then replay cached actions without inference on cache hits. Read how it works on iOS and Android π clstk.com/4i1onKP
react-native-arrangement-view now runs on @TesterArmyβs e2e + @agent_device, folding the device and testing different postures
Great explainer on e2e, a testing framework by @TesterArmy powered by @agent_device on mobile
Introduction to Verification Engineering In this video, you'll learn: β How to build an agentic loop with @TesterArmy's e2e open source testing framework β Run this loop on every PR β What makes e2e different: deterministic AND agentic β The future of agentic development
@matzatorski @TesterArmy @e2e @o_kwasniewski Sir, youβre now a user of agent-device, welcome!

@stringsaeed @poteto e2e uses agent-device as a driver - same tool, better experience :)
Both e2e and @t3codes build on agent-device. What will you build?
agent-device is in the weights of @apex__ai. use it for QA testing and exploration too

Great to see @agent_device powering the app interaction in @expo bug-fixing workflow. Reproduce the crash, fix it, verify it on EAS Simulator. Bring back recordings for a human to review. Check it out! β¬οΈ expo.dev/blog/agent-fixβ¦
