VSTest with xml/json reports obtained from Katalon

We are looking for your help to use the module VSTest – TestAssemblies.

Let me summarise our workflow before asking the question. We are trying to automate our tests. In order to do it, we decided to record the interaction with the browser through a 3rd party software. We managed to successfully integrated TFS and the 3rd party software: this means that when someone runs a test in TFS, underneath the hood TFS launches the 3rd party software and makes it repeat the recorded instructions, finally the 3rd party software saves the reports as .xml or .json files. For completeness, the 3rd party software that we use is Katalon.

We’d like to publish the reports using the module VSTest – TestAssemblies. It is my understanding that this module takes as input the results of a test run, then converts it to a .trx file and finally publishes statistics and analytics. The 3rd party sw that we use saves the results in an xml or json file, therefore the .trx file that TestAssemblies generates is empty and invalid. Is there any way to make TestAssemblies support .xml/.json files? What are the formats that TestAssemblies supports?

Thanks a lot in advance for your help Luigia
