Appium Architecture

This segment of the Appium testing guide provides insights into the architecture of the Appium framework. The Appium Architecture comprises three key components:

  • The Appium client comprises scripted automation code written in widely used programming languages like Java, Python, Ruby, Perl, and others. These automation scripts contain configuration details relevant to the target device and the application being tested. During the execution of test cases, Appium utilizes these scripted codes and configurations to conduct the tests.
  • Appium Server: The Appium server acts as an HTTP server that receives command requests in JSON format from the client. Built on Node.js, the Appium server processes these commands and executes them on the mobile devices connected to it. To run the test scripts successfully, it is recommended to have the Appium server installed on the local machine.
  • The term “End Device” pertains to the devices on which the Appium server executes the tests. This encompasses emulators, simulators, and physical devices that are connected to the Appium server. These end devices serve as the testing environment where automation tests are conducted.

Appium testing on LambdaTest 

LambdaTest, a cloud-based AI-powered test orchestration and execution platform that offers a practical solution for parallelization.
