Unfortunately, you can only test an iOS application using macOS. If you wish to setup your macOS environment for Katalon Studio, please refer to this guide.
Due to the diifferences in computer environments, the Katalon download package does not include some dependencies needed to test on mobile devices/emulators. Thus, in order to succesfully create and run a test case using Katalon Studio on Windows, you will need Appium.
Make sure you install Node.js into a location where you have full Read and Write permissions.
Install Android SDK: Katalon Studio will detect and ask you to install Android SDK automatically if your current machine doesn’t have it. Please allow Katalon Studio to install it in this case.
For more information on how to run a test suite, check out the documentation here.
