[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.

01

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.

02

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.

03

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.

04

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.

GitHubConnect 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.

DashboardGitHub ActionExpo EAS

Write tests in plain English

Describe the journey in natural language. "Sign up with email, complete onboarding, add an item to the cart." No testID props, no selectors, no Detox config.

Introducing Scout: API Testing Built for AI Agents

We built Scout, an open source CLI that gives coding agents a safe harness for testing APIs. Point it at an OpenAPI spec and it sweeps, fuzzes, and records findings - with guardrails on by default. In this walkthrough it finds three real bugs in the Swagger Petstore.

How Do We Use TesterArmy at TesterArmy?

We ship TesterArmy with TesterArmy. Here is how we dogfood our own QA agent - what we test, how we wire it into PRs, and what it catches.

[07] FAQ

React Native testing, answered

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 guides, or the broader mobile app testing overview.
