Appium is an open-source test automation tool for mobile applications on iOS mobile, Android mobile, and Windows desktop platforms. It is also composed of mobile web apps that are web apps accessed using a mobile browser. Specifically, it includes appium supports Safari on iOS and Chrome or the built-in ‘Browser’ app on Android. It allows you to test all three types of mobile applications: native, hybrid, and mobile web. Native apps are those written using iOS, Android, or Windows SDKs. Hybrid apps have a wrapper around a “web-view” — a native control that enables interaction with web content. Projects like Apache Cordova or Phonegap make it easy to build apps using web technologies that are then bundled into a native wrapper, thus, creating a hybrid app.
Appium Testing allows you to run the automated tests on actual devices, emulators, and simulators. Also, automating hybrid and native mobile applications for Android and iOS is a key function handled by Appium, a node.js server. One of the core tenets of Appium is that test codes can be written in any framework or languages like Ruby on Rails, C#, and Java without having to modify the apps for automation purposes. The interaction between node.js server and Selenium client libraries is what ultimately works together with the mobile application. Appium is also open-source and can seamlessly run on a variety of devices and emulators, making it an apt choice for mobile test automation. It also supports Android and iOS-based apps, but support for Firefox mobile OS is in the pipeline.
How does it work?
Appium app is a server. The server is written in Node.js and implements the Selenium WebDriver as well. It allows one to use available WebDriver client to fire your tests. And then, your mobile app acts precisely like a web app where the DOM is by View hierarchy.
Process of testing with appium:
- Interlinked the real device with PDAnet.
- Starting with the appium server & Eclipse to run the app.
- Start the inspector session from appium server.
- Append desired capabilities & begin the session.
- App reloads in device & appium server shows UI Automator.
- In a real device, manually open the feature which needs to test.
- Click the feature on appium virtual device which needs to test & get the id /XPath or required data.
- Use those data on the script. The script is also by Java.
- Run the script.
- Get the result on a real device.
Fundamental Requisite for Appium (Android System Setup Requirements):
- Android SDK & Java should be inducted correctly.
- Appium setup for Android as well as iOS on OS X, Linux, and Windows.
- Identify and also explain the desired potentials for writing the Appium test.
Benefits of Appium testing:
◾Underpins automation of Hybrid, Native, as well as Webapps.
◾Underpins the vast majority of programming languages like Java, Ruby, Python, C#, etc.
◾It’s an open-source tool.
◾Support for both stages Android as well as iOS.
◾Handles simulators/emulators and real devices.
However, most of the tools require an additional agent that needs to be compiled with most of the application code so that the tool can communicate with the native mobile app.
