without the flake
TesterArmy runs automated end-to-end tests on your React Native app - iOS and Android, bare or Expo - from plain-English descriptions. No Detox, no testIDs, no test code.

[03] The framework tax
Your E2E suite works,
until React Native moves
Every React Native release, native module bump, and OTA update is a chance for the UI to drift away from your test suite. Maintaining the harness becomes the job.
Detox setup is a project of its own
Native build configs, synchronization hacks, testID props sprinkled through every screen. The suite takes weeks to stand up and one RN upgrade to fall over.
Upgrades break UI your tests can't see
A React Native or New Architecture upgrade shifts layout, timing, and native modules at once. Unit tests stay green. The regression ships in the next release build.
OTA updates skip your test pipeline
EAS Update and CodePush push JS straight to production devices. The binary was tested at submission. The bundle running today wasn't.
Flaky E2E erodes trust until nobody reads it
When the suite fails on animation timing twice a week, red stops meaning broken. The one real regression scrolls past in a wall of retries.
[04] Per-regression evidence
Every regression, fully recorded
When a journey breaks, you don't get a crash log and 'works on my device'. You get the recording from the simulator, screenshots at every key moment and the step trace with timing.
- 01Full session recording of every run on a real simulator
- 02Screenshots, named by the journey description
- 03Pass/fail breakdown per step with timing data
- 04Repro steps and the exact commit SHA that broke the flow
- 05Side-by-side diff against the last green run
[05] How it works
Four steps to automated React Native app testing
Upload a build, describe critical flows in plain language, and let TesterArmy catch regressions on every PR - before your users or the app stores do.
Connect GitHub
Upload app binary
Upload your build
Drop an .app or .apk into the dashboard, or wire up the tester-army GitHub Action. Bare React Native and Expo builds work the same way - we test the compiled binary.

August 26, 2026Introducing unbox-ai: See Where Your Agent's Tokens Actually Go
We built unbox-ai to read our own QA agent's traces. One command opens a token treemap, a latency waterfall, and a scrubbable timeline of the run. The same binary is a read-only trace explorer your coding agent can use. Now it's open source.
August 20, 2026Introducing the Issues Tab: One Row Per Bug, No Matter How Many Runs Found It
Agent-found bugs now land in one deduplicated list instead of scattered run reports. Every issue carries expected vs actual, repro steps, and a replay of the exact moment it broke - and leaves the list as a Linear ticket, a prompt for your coding agent, or resolved.
August 18, 2026We Benchmarked 10 Vision Models on Clicking What They See
All ten models answered every visual understanding question correctly. Grounding the click is where the field splits, and where GPT-5.6 Luna won on accuracy, precision, and cost.

Frequently Asked Questions
Automated React Native testing runs your compiled iOS or Android app end to end - tapping, typing, and verifying real user flows - without a human driving the device. With TesterArmy, an AI agent executes flows you describe in plain English on cloud simulators, so you get E2E coverage without writing or maintaining Detox, Appium, or Maestro tests.
No. TesterArmy replaces the framework layer entirely. There is no test code in your repo, no native build configuration, and no runner to keep in sync with React Native upgrades. You describe journeys in plain English and we run them on every build.
No. The agent sees the screen the way a user does - it doesn't locate elements by testID or accessibility selectors, so you don't need to instrument your component tree or keep IDs stable across refactors.
Yes. We test the compiled binary, so Fabric, TurboModules, bridgeless mode, and your React Native version are transparent to us. Upgrades that silently shift UI behavior are exactly what journey tests catch.
Yes. Upload the build with the new bundle - or point a run at a build channel - and the same journeys run against the updated JS before you promote it to production devices.
Yes, with a first-party integration. EAS builds flow straight into TesterArmy and tests run on every build. See the Expo app testing page and the Expo EAS docs for the full setup.
Maestro is a framework - you write YAML flows, maintain them through UI changes, and run the infrastructure. TesterArmy is a service - plain-English journeys, cloud simulators, maintenance handled, evidence on every build. Teams migrating from Maestro usually port their whole suite in an afternoon.
Your users run the binary, not your unit tests
React Native testing shouldn't mean babysitting a Detox suite. TesterArmy runs the flows that matter on every build - iOS and Android, bare or Expo - and ships evidence when something breaks. On Expo? See Expo app testing and the EAS integration docs. Migrating a suite? Start with the Maestro or Appium migration playbooks, or the broader mobile app testing overview.
