Our usage was at least seven to eight months ago. We have web-based and desktop Windows applications, and automating the desktop applications was challenging. Ranorex provided the necessary keywords, especially for our shallow testing needs.
We did a couple of POCs using this solution. But at the end of the day, we went on with creating our own framework. So, we used it for a POC to check its working and feasibility analysis within our organization.
Ranorex is what we found more secure. They allowed installation on your machine, and the reports don't go to the internet. Being in a financial organization, we want our reports to remain confidential, not part of the public domain or public cloud. So that was one thing.
Besides the flexibility that Ranorex offers, I'm an automation developer, and I appreciate the flexibility in terms of customization and other features. On the other hand, Katalon, or Test Project, uploads results to the public cloud and has a dependency on adding your own keywords and functions.
