This will show you how I managed to use Applitools within Katalon Studio. Applitools is a visual testing and monitoring service. In this demo, a Test Case instanciates an Applitools’ Eyes object and calls its methods. The Eyes object takes screenshots of AUT and transfer images to the Applitools service where various testing/monitoring features are offered.
It worked for me.
The combination of Applitools and Katalon Studio looks attractive to me.
