One of WebdriverIO's most powerful capabilities is its integration with Appium for mobile testing. Using the same framework for browser automation and mobile testing means your team shares knowledge, tooling, and even some code across platforms. This guide covers setting up WebdriverIO with Appium to test iOS and

Running Detox tests locally is one thing. Getting them running reliably in CI is another. Mobile E2E tests have historically been the most painful part of CI/CD pipelines: emulators crash, builds are slow, and tests that pass locally fail for reasons that are hard to diagnose. This guide covers
Testing
Unit tests are the foundation of a React Native test strategy. They run fast, give immediate feedback, and catch logic errors long before they reach a device or simulator. Yet many React Native teams skip them or write tests that test nothing meaningful. This guide covers the practical patterns you
Testing
Native modules are the bridge between your JavaScript code and platform APIs — camera, geolocation, biometrics, push notifications, Bluetooth. They're essential for real apps, but they're also the reason React Native unit tests break: native modules don't exist in a Jest environment running on Node.
Testing
When it comes to end-to-end testing for React Native apps, two frameworks dominate the conversation: Detox and Appium. Both can drive real devices and simulators. Both support iOS and Android. But they take fundamentally different approaches, and that difference matters enormously for React Native projects specifically. This article breaks down
Testing
Android testing is layered. Your app has units of business logic, UI components that respond to state, and end-to-end flows that span multiple screens. Each layer needs a different kind of test. This guide covers the full Android testing stack: unit tests, integration tests, and UI tests — when to use
Testing
Appium and Espresso are the two most popular frameworks for Android UI testing. They can both automate your app and verify user flows — but they do it in fundamentally different ways, and choosing the wrong one costs real time. Here's the breakdown. The Core Difference Espresso runs inside
Testing
Apple's built-in testing framework is XCTest. It handles both unit tests and UI tests — and since Xcode 15, the tooling around it has never been better. If you're developing native iOS apps in Swift, XCTest is the place to start. This guide covers unit testing with
Testing
Mobile apps fail in ways web apps don't. Network switches mid-session, back button behavior, keyboard covering inputs, push notification interruptions, backgrounding and foregrounding — all of these are uniquely mobile problems that manual QA eventually misses. Mobile test automation is how teams ship mobile apps confidently. This guide covers
Testing
Python is one of the most popular languages for test automation, and Appium has a first-class Python client. If your team already writes API tests or browser tests in Python, you can extend that work to mobile apps with the same tools and patterns. This guide covers Appium with Python
Testing
Espresso is Google's official UI testing framework for Android. Unlike Appium, which runs as an external server, Espresso runs inside the app process. This makes it significantly faster and more reliable — no network overhead, no timing guesses, no session management. If you're testing a native Android
Testing
Appium is the most widely used framework for mobile app automation. It lets you write tests once and run them on Android and iOS using the same API — whether your app is native, hybrid, or a mobile web app. This tutorial walks you through everything: installing Appium, setting up your
