Mobile app testing can feel like an uphill battle at times. But with the right tools like Appium 2.x, you can climb every mountain and test across the seven seas. Real Device Cloud propels testing into a new dimension by providing an adaptable and efficient platform for testing on genuine devices.

    Real device clouds like LambdaTest are your Avengers in simplifying mobile app testing. With just a snap of your fingers, they assemble a mighty team of real devices for you to run automated Appium scripts on. So whether you’re testing a consumer app or an enterprise solution, you can cover more ground than Thor flying across the nine realms.

    In this guide, we’ll share insights on configuring Appium 2.x. We’ll provide tips to help you avoid common pitfalls that can ambush your app testing efforts.

    Appium 2.x Architecture

    The Appium 2.x architecture is made up of three main components that hook up to enable automated mobile app testing:

    Appium Client

    The Appium client contains all the test scripts and the code written in programming languages like Java, Python, Ruby, etc. These scripts set forth the test cases and workflows that will be carried out. They also contain configuration details that lay out specifics around the target device, platform, app parameters, etc. Essentially, the client scripts set the wheels in motion for the testing by instructing how the automation will be run.

    Appium Server

    This powerful server acts as the brains behind Appium test execution. It is written in Node.js and handles all of the test script requests coming in from the client. The server fleshes out the client commands and routes them to the right endpoints. It does this by converting the Selenium-based commands into the native syntax required by the platform-specific frameworks. For Android, the server translates to UiAutomator2 API calls. For iOS, it maps to XCUITest APIs. This middleman server enables the client scripts to cut through the noise and seamlessly trigger automation on both platforms.

    ●  End Devices

    These are the actual hardware or emulated devices where the rubber meets the road when tests are executed. The end devices contain the platform-specific frameworks that the Appium server taps into to coordinate test execution on the device. For iOS, there is XCUITest baked into Xcode. For Android, there is the UiAutomator2 framework available. Once the Appium server funnels down the client script actions, the end device frameworks take over and round out the automation by interfacing with the operating system and app-in-test. Results are then bubbled back up through the same channel.

    So, in summary, Appium provides a straightforward way to tap into native test automation frameworks across different mobile platforms. The client scripts kick off the testing, the server acts as commander-in-chief to relay the instructions down, and the end devices are the foot soldiers that ultimately carry out the mission. This clean architecture allows Appium to enable polyglot test automation for apps on both Android and iOS.

    What is new in Appium 2.x?


    Plugins allow developers to extend and customize Appium functionality to suit their specific needs. You can tap into Appium’s extensibility by building and integrating your plugins. Some capabilities include:

    • Install new plugins to augment Appium with additional features and capabilities on top of the core offering. This makes it easy to tailor and shape Appium to align better with your mobile testing workflow and objectives.
    • Update existing plugins to take advantage of new functionality and fixes. Appium plugins can evolve, just like Appium itself.
    • Uninstall plugins that are no longer relevant or needed. Pruning unused plugins helps declutter your Appium implementation.


    Appium 2.x offers more control over drivers. You can install additional drivers beyond just the core set that is bundled with Appium. This paves the way for you to drum up driver support for entirely new platforms and devices that Appium does not yet support out of the box.

    You also have access to driver configuration commands. This allows you to fine-tune driver settings instead of just accepting default values. Giving testers the capability to take the driver reins enables deeper customization of Appium’s automation capabilities for particular testing needs.

    Configuration File

    Appium 2. x introduces a centralized configuration file for setting your Appium server preferences and defaults upfront. This can save you from repeatedly specifying the same flags and options every time you start up the Appium server.

    Some key advantages include:

    • Define your ideal server configuration upfront in a JSON, JS, or YAML file rather than passing arguments manually each time.
    • Spin up Appium server sessions more quickly since the config is already defined and ready to go.
    • Change server defaults and settings by simply editing the config file rather than digging into messy server startup scripts.

    Getting started with Mobile App Testing on Appium 2.x on LambdaTest Cloud Platform

    Attempting to install Appium 2.x along with all its dependencies can quickly go off the rails and turn into a headache. You need to gather up all the ingredients like Node.js, Android SDKs, Xcode, Java, etc. Even once you have everything in place, configuration, and setup can be fragile and flaky. Details like OS versions, environment variables, and platform tooling can easily throw a wrench in your plans if not perfectly aligned.

    Before you know it, you’ve wasted hours tinkering around and are still no closer to actually being able to use Appium for testing. And don’t even get me started on the device management overhead if you try to build your in-house device lab! Maintaining a complex matrix of real devices across different OS versions is a maze that few have successfully navigated.

    Luckily, there is a smooth highway toward Appium testing – LambdaTest’s real device cloud! LambdaTest lets you kiss those Appium installation frustrations goodbye by providing instant access to a robust cloud of 3000+ real test devices.

    With LambdaTest, you simply spin up the precise real devices you need on demand. LambdaTest’s built-in Appium integration then allows you to pump your test scripts directly to the devices without any messy setup or installation required on your end.
