[03] The Expo gap

Fast releases,
untested releases

EAS makes shipping an Expo app effortless - builds, updates, and submissions on tap. The testing step never got the same upgrade. Until now.

01

E2E frameworks want you to eject

Detox needs config plugins, custom dev clients, and native build tweaks. The whole point of Expo was not doing that. So most Expo apps ship with no E2E coverage at all.

02

EAS Update ships JS in minutes, untested

Over-the-air updates skip App Review and your test pipeline in one move. The bundle your users run tonight has never been through a full journey.

03

Simulator builds pile up unverified

EAS produces a build for every profile and branch. Someone taps through the happy path on one of them, sometimes. The rest go straight to TestFlight.

04

SDK upgrades move everything at once

A new Expo SDK bumps React Native, native modules, and tooling together. Unit tests stay green while navigation, permissions, or deep links quietly break.

[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 build that broke the flow
  • 05Side-by-side diff against the last green run
[05] How it works

Four steps to automated Expo app testing

Connect EAS, describe critical flows in plain language, and let TesterArmy catch regressions on every build and OTA update - before your users do.

Run on every EAS build

Every EAS build - or every PR via the GitHub Action - triggers a full journey run on cloud iOS simulators and Android emulators. Results in minutes.

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.

[07] FAQ

Expo app testing, answered

Connect your Expo account to TesterArmy and new EAS builds sync automatically. Each build triggers the journey tests you defined in plain English, on cloud iOS simulators and Android emulators, and returns a report with recordings and screenshots. No CI scripting required - though a GitHub Action is available if you want PR checks.
No. TesterArmy tests the compiled binary EAS produces - there is nothing to install in your app, no config plugin, no custom development client, and no native code changes. Managed workflow stays managed.
Yes. Run your journeys against a build pointed at the update branch before you promote it. OTA updates skip App Review, which makes them the release channel that most needs a test gate.
Most teams run journeys on a simulator build from their preview profile on every PR, and on the release candidate before submission. Any profile that produces an iOS simulator or Android emulator build works.
Detox can be made to work with Expo through config plugins and a custom dev client, but it adds the native build complexity Expo exists to remove. TesterArmy needs none of that - describe the flow in plain English and it runs against the EAS build as-is.
Automated Expo app testing runs your compiled Expo app end to end - onboarding, auth, purchases, navigation - without a human tapping through it. TesterArmy's AI agent executes plain-English journeys on every EAS build and reports regressions with full recordings, so SDK upgrades and OTA updates stop being leaps of faith.

Every EAS build tested before anyone installs it

Expo removed the native build pain. TesterArmy removes the testing pain. First-party EAS integration, plain-English journeys, and evidence on every build - managed workflow included. Setup lives in the Expo EAS docs. Bare workflow? See React Native app testing or the broader mobile app testing overview.
