What is Appium testing and why is it so popular?
Appium is a mobile automation tool that uses Node.js to operate as an HTTP server. It supports simulators and emulators and processes HTTP requests from Selenium client libraries differently based on the platforms. One of the best things about Appium is that it lets you write in any language supported by Selenium using WebDriver API. Appium translates Selenium Webdriver commands into UIAutomation (iOS), or UIAutomator (Android) commands, making it independent of the mobile operating system. Automation scripts can be run on real Android and iOS devices using the WebDriver JSON Wire protocol. When testing an Android app, Appium automates it with the help of the UIAutomator library, while on iOS, it proxies commands to a UIAutomation script running in instruments.
Overall, Appium testing is widely adopted by modern enterprises to create a comprehensive mobile automation framework due to its growing user base, strong community, and flexibility.

1. Run tests with Appium on Android devices
Appium is an automation testing tool designed to test Android applications. It leverages the UIAutomator framework or Selendroid to automate user interface testing on Android devices. To achieve this, Appium uses the bootstrap.jar file as a TCP server, which sends test commands to interact with the Android device through the UIAutomator or Selendroid framework.
To test Android applications using Appium, you must install the necessary components on your system. The following steps outline the installation process:
- Firstly, download the Appium Jar files for Java, the latest Appium Client Library, and the Appium Server.
- You will also need to download and install Java on your system. Be sure to set the environment variables correctly.
- Additionally, TestNG, a testing framework for Java, is required to run Appium tests. Make sure to install it as well.
- Once all components are downloaded and installed, enable Developer Mode on your Android device and configure it for testing.
Following these steps will enable you to begin testing Android applications using Appium with ease.
Below is an example code that demonstrates how to write Appium test scripts for testing Android applications. The code uses Eclipse IDE to run the tests on Android devices.
When it comes to test automation using Appium, it's crucial to specify the desired capabilities. These capabilities can be defined either in the test code or in appium.txt files. Essentially, the desired capabilities represent a JSON object consisting of keys and values sent from the client to the server. By creating a session for a browser with a specific set of desired capabilities, testers can gain greater control over the server during test automation. This enables them to achieve more efficient and effective Appium testing.
2. Perform Appium testinng on iOS devices
For iOS device testing, Appium employs the JSON wire protocol, just like it does for Android devices. In this case, it utilizes Apple's UIAutomation API to interact with the user interface elements to automate iOS device testing. To achieve this, Appium uses the bootstrap.js file as a TCP server that sends test commands to the iOS device through Apple's UIAutomation API framework. This enables testers to automate iOS device testing in a highly efficient and effective manner.
What made Appium the testing tool of choice for iOS devices?
Appium is an excellent choice for automating iOS app testing due to the following features:
- Appium is an open-source framework that eliminates the need for costly licensing fees associated with other testing tools and frameworks.
- With its built-in XCUITest driver, Appium generates detailed information logs with a comprehensive reporting structure. This enhances test result analysis and simplifies debugging efforts.
- Appium allows for code reusability written for iOS devices on Android devices, saving valuable time and effort for hybrid app testing.
- Appium enables users to test applications on various versions of iOS devices, ensuring cross-platform compatibility for apps.
- Appium provides real-time monitoring of tests on real iOS devices, providing a reliable testing environment.
Creating the iOS Appium Test Script
Create a new project in Eclipse and package/class to begin writing the Appium Test Script.
To open the Google Chrome app on an iPhone for testing, the tester must set the Desired Capabilities and instantiate the Appium Driver in the script.
When writing Appium test scripts for iOS devices, testers must use the UDID of the iPhone, iOS version, and bundle ID details (in this case, for the Google Chrome app) to set the Desired Capabilities as well as instantiate the Appium Driver. Running this script will open the Google Chrome app on the connected iOS device, allowing for automated testing to be carried out.
