Appium is an open-source framework for automating mobile apps. It drives native, hybrid and mobile web apps on iOS and Android through the WebDriver standard, using drivers such as XCUITest for iOS and UiAutomator2 for Android, and works with Java, JavaScript, Python, C# and Ruby.

Why choose Appium for mobile test automation?

Because one suite can cover both iOS and Android, in a language your team already uses, without changing your app’s code. It works with native, hybrid, React Native and Flutter apps, and runs on emulators, your own devices or any major device cloud.

Appium or Espresso and XCUITest?

Espresso (Android) and XCUITest (iOS) run inside the app, so they’re faster for very large single-platform suites. Appium is the better choice when you want one suite for both platforms, or when testers work outside the app’s codebase. If native tools fit better, we’ll tell you, and we can migrate.

Can Appium test React Native and Flutter apps?

Yes. We test React Native and Flutter apps with Appium. For React Native teams who want tests inside the codebase, Detox is another option we can recommend.

Do you test on real devices?

Yes. We run on real devices through BrowserStack, Sauce Labs, LambdaTest, AWS Device Farm or Firebase Test Lab, or in your own device lab, and use emulators and simulators in CI for fast feedback.

Can you test gestures, permissions and push notifications?

Yes. We automate gestures, permission prompts, deep links and push notifications, and mock biometrics, camera and GPS where the scenario needs it.

Can you test in-app purchases and payments?

Yes, in sandbox and test environments: purchases, subscriptions, checkout, failed and refunded payments, and restoring purchases.

Which languages and test runners do you use?

Java with TestNG or JUnit 5, Python with pytest, C# with NUnit, and JavaScript with WebdriverIO or Mocha. We match the language your team already uses.

How do you structure an Appium framework?

Usually with a Screen Object Model, shared steps across platforms, environment and device configs, and data-driven tests. If your team prefers BDD, we add Cucumber so scenarios read in plain language.

How do you fix a flaky Appium suite?

We find the causes first, such as brittle locators, fixed waits, shared data or device issues. Then we fix them, add stable test IDs with your developers where possible and tune parallel runs, rather than adding retries.

Can you upgrade our suite from Appium 1 to Appium 2?

Yes. We move you to Appium 2 and its current drivers, update capabilities and plugins, and fix anything that changed, while keeping your tests running.

Do you use AI with Appium?

Yes. We use AI tools such as Qagentify to draft tests and suggest fixes for broken locators. An engineer reviews every change before it’s merged.

What is the free Appium framework audit?

We review your existing Appium suite, or your plan for one, and send you a short report on structure, flaky tests, device coverage, run time and CI setup, with the changes we’d make first. There’s no obligation.

You do. Everything is written in your repository, in your language, with documentation, so your team can keep it running without us.

How long does it take, and what does it cost?

It depends on your app, platforms, devices and whether we’re building new or taking over a suite. We agree the scope first, then send a timeline and a fixed quote.

[ What Appium is, and why it matters ]

One open-source framework for every kind of mobile app

Appium is an open-source framework for automating mobile apps. It speaks the same WebDriver standard as Selenium, and uses platform drivers, XCUITest for iOS and UiAutomator2 for Android, to control native, hybrid and mobile web apps. It doesn’t need changes to your app’s code, and tests can be written in Java, JavaScript, Python, C# or Ruby.

That makes it the most flexible way to automate mobile testing across both platforms. Like any mobile tool, it needs careful design to stay fast and stable.

The problems it solves

Two platforms, double the work

Testing every release by hand on iOS and Android doubles effort and still misses things.

Too many devices

Phones, OS versions and screen sizes multiply faster than any team can check manually.

Hard-to-repeat scenarios

Gestures, permissions, notifications and payments are slow and error-prone to test by hand.

Slow release cycles

App store reviews leave little room for bugs found late.

[ How it gives you an advantage ]

Appium, Espresso, XCUITest and Detox, side by side

Appium wins on reach and flexibility. Native tools win on speed for single-platform suites. We’ll tell you honestly which fits your app.

Aspect	Appium	Espresso	XCUITest	Detox
Platforms	iOS and Android	Android only	iOS only	React Native apps
Languages	Java, JavaScript, Python, C#, Ruby	Java, Kotlin	Swift, Objective-C	JavaScript, TypeScript
One suite for both	Yes	No	No	Yes, for React Native
Speed	Slower: drives the app from outside	Fast: runs inside the app	Fast: runs inside the app	Fast: syncs with the app
Needs app source code	No	Yes	Yes	Yes
Best for	Cross-platform suites and black-box testing	Large Android-only suites	Large iOS-only suites	React Native teams

One suite, two platforms

Shared steps for iOS and Android, with platform-specific screens only where needed.

No app changes needed

Tests drive the app from outside, so testers don’t need your source code.

Your language

Java, JavaScript, Python, C# or Ruby, with the runners your team knows.

Runs anywhere

Emulators, simulators, your own devices or any major device cloud.

Honest note: Appium is slower than Espresso or XCUITest for very large single-platform suites. When native tools or Detox fit better, we recommend them and can migrate your tests in priority order.

[ Where it can be used ]

Where Appium fits best

Any app your users run on a phone or tablet. These are the cases where one cross-platform suite pays off most. More on Android and iOS app testing.

Consumer apps on both stores

One suite covering the same journeys on iPhone and Android.

Fintech and real-money apps

Wallets, payments, payouts and in-app purchases checked on every build.

eCommerce and delivery apps

Search, cart, checkout, tracking and push notifications.

React Native and Flutter apps

Cross-platform apps tested the way users actually see them.

Hybrid apps and PWAs

WebViews and mobile web tested alongside native screens.

Tablet and iPad apps

Layouts, rotation and split views on larger screens.

[ How we use Appium ]

Eight Appium solutions we deliver

Start with your key journeys on both platforms, then add the layers your app needs. Each card lists what we deliver, when you need it and the problem it prevents.

Cross-platform app automation

One suite, iOS and Android

One Appium 2 suite for your iOS and Android apps, using the XCUITest and UiAutomator2 drivers, with shared steps and platform-specific screens only where they differ.

What we deliver

Native iOS and Android apps
Hybrid apps with WebViews
React Native and Flutter apps
Phones and tablets, including iPad

When you need it

When you ship on both platforms and want one suite to maintain.

The problem it preventsTwo separate test suites drifting apart as the app changes

Real-device & emulator execution

Cloud, lab or CI

Tests run on emulators and simulators in your CI for fast feedback, and on real devices in a cloud or your own lab before release, in parallel.

What we deliver

BrowserStack, Sauce Labs, LambdaTest, AWS Device Farm or Firebase Test Lab
Your in-house device lab
Emulators and simulators in CI
Parallel runs across many devices

When you need it

When your users are spread across many phones, OS versions and screen sizes.

The problem it preventsA release that works on the latest phone and crashes on the ones most users have

Mobile web testing

Safari and Chrome

Your website or web app tested in mobile Safari and Chrome on real devices, with the same framework as your native app tests.

What we deliver

Mobile Safari on iPhone and iPad
Chrome on Android
Responsive layouts and touch journeys
Shared page objects with app tests

When you need it

When a big share of your traffic comes from phones.

The problem it preventsMobile visitors finding broken layouts and journeys first

Device features & gestures

Real-world behaviour

We automate the parts of mobile apps that are hardest to test by hand, from gestures and permissions to deep links, notifications and mocked device sensors.

What we deliver

Swipe, scroll, pinch and long-press gestures
Permission prompts, deep links and push notifications
Biometrics, camera and GPS mocking
Backgrounding, rotation and network changes

When you need it

When your app depends on device features, not just screens.

The problem it preventsFeatures that only fail on a real phone, in a real situation

In-app purchases & payment flows

Money paths

The journeys that make you money tested end to end: subscriptions, in-app purchases and checkout, in sandbox and test environments.

What we deliver

In-app purchases and subscriptions
Checkout and payment provider flows
Failed, cancelled and refunded payments
Receipts, entitlements and restore purchases

When you need it

When revenue depends on purchases inside the app.

The problem it preventsCustomers charged but not given access, or not charged at all

API checks & data-driven tests

Faster, wider coverage

View service

API checks run next to your app tests and set up test data, so UI tests stay short. Data-driven tests cover many inputs from one scenario.

What we deliver

API contract and payload checks
Test data created through the API
Data-driven tests across many inputs
App and API results in one report

When you need it

When your app depends on APIs that change often.

The problem it preventsSlow UI tests doing work an API call could do in seconds

Visual & accessibility checks

Screens and a11y

View service

Screenshots of key screens are compared across devices to catch layout changes, and accessibility checks flag missing labels and other common issues.

What we deliver

Screenshot comparison per device and OS
Text scaling and dark mode checks
Missing labels for screen readers
Results that feed manual accessibility testing

When you need it

When design consistency and accessibility matter on every device.

The problem it preventsA layout change breaking screens on small or large phones

Suite rescue, Appium 2 upgrade & AI assist

Stabilise and modernise

We fix flaky mobile suites at the cause, upgrade Appium 1 suites to Appium 2, and use AI tools such as Qagentify to draft tests and suggest locator fixes, with an engineer reviewing every change.

What we deliver

Root causes of flaky tests found and fixed
Upgrade from Appium 1 to Appium 2 drivers
Stable locators and proper waits
AI-drafted tests and fixes, engineer-reviewed

When you need it

When your team has stopped trusting the mobile suite.

The problem it preventsReal bugs ignored because “that test always fails on iOS”

[ Our approach ]

How we analyse your project and design the solution

Mobile suites fail when they’re built screen by screen without a plan. We start with your users, their devices and the people who will maintain the tests.

STAGE 01

Understand your app and users

We map key journeys, the devices and OS versions your users actually have, and where bugs have hurt your ratings before.

You get: Journey and device map

STAGE 02

Review what exists

If you have a suite, we measure flakiness, run time and device coverage, and decide what to keep, fix or retire.

You get: Suite health report

STAGE 03

Match your team and app

Language, runner and drivers chosen to fit your developers and your app type, from native to Flutter.

You get: Stack decision

STAGE 04

Design the architecture

Screen objects, shared steps, device configs, test data and where each test runs, planned up front.

You get: Framework blueprint

[ Benefits you’ll see ]

What changes once the framework is in place

Testers spend their time exploring new features and edge cases, while repeat checks run automatically on every build.

One suite to maintain

Shared steps across iOS and Android mean one change fixes both.

More devices covered

Parallel runs on clouds or your lab reach far more phones than manual testing can.

Hard scenarios automated

Gestures, permissions, notifications and payments checked on every build.

Earlier feedback

Emulator runs in CI catch problems before a build reaches testers or the stores.

Clear reporting

Allure or Extent reports with screenshots, plus results in TestRail, Xray or Zephyr.

Yours to keep

Your repository, your language, documented, with no licences to buy.
