However, let’s start with a quick introduction with Appium.

What is Appium?

Appium is an open-source User Interface testing framework for mobile applications. Appium supports all native, hybrid and web application testing on physical devices as well as an emulator. It offers cross-platform application testing; it works for both Android and iOS platform test scripts. It is so flexible on any mobile device operating systems. Amazingly, Appium supports all languages that have Selenium client libraries like- Java, JavaScript with node.js, PHP, Objective-C, C#, Ruby, Python, etc.

How APPIUM Works?

When I came across Appium, I wondered how it works, and to my surprise, it’s very logical and pleasant.

Appium is an ‘HTTP Server’ written using Node.js principles and handles Android, and iOS session with Webdriver JSON wire protocol.Node.js must be pre-installed on the system for the Appium Server to work. 

When Appium is installed, then we have ourselves a server that exposes a REST API. Awesome!! 

Now, this is where the action is,

It accepts connection and command request from the client and executes that command on mobile devices (Android / iOS).

It responds with HTTP responses, for these requests to be executed, it utilises the test automation frameworks mobile to drive the user interface of the apps.
