Getting Started With Mobile Automation Using Katalon Studio – The Free Automation Tool


Test Automation refers to automating the testing process of applications. Katalon Studio is one of the popular tools software testing companies use to automate web and mobile applications. In this tutorial, we will be seeing how to get started with the tool. 

Tool Description

Katalon studio is an open source automation tool which can be used for testing web, mobile application and API testing.

It is developed on top of the open source automation frameworks such as selenium and appium.

Groovy, Java and JavaScript are the main scripting language which can be used to write script in Katalon studio.

Katalon script runs in all modern browsers. Test reports will be generated in the Katalon studio once the script completes its execution. These reports can be exported as HTML, PDF…etc.

Indium follows a process-oriented approach for the successfull deployment of Test Automation

Dependencies Required for Mobile Automation Using Katalon Studio

Katalon Studio



Android device with enabled developer mode and Android sdk

Need of Appium and Node.js

Appium is a server written in Node.js. This is used to automate hybrid and native mobile applications.

Appium handles multiple webdriver sessions. This provides cross platform testing i.e. it works for both android and ios apps.

This is used to translate webdriver commands to UIAutomator or UIAutomation depending on the device type.

Since Appium written in Node.js, we need node to run it .So it is required to install node.js. Node.js is a JavaScript runtime environment which can be used to execute JavaScript from outside the browser.
