First of all, please try again with latest Katalon Studio 5.2 version. Secondly, is there any special configurations from your Linux server, I see that there are some logs regard to HTML reports such as ‘Arching HTML reports…’
From what I see in Windows, there is no support for multiple test suites showing results in one report file either, you need to press the “eye” icon and select each report by itself, can we have a report.html file created from all running Test Suites in the Test Suite Collection?
So seems like issue is not in the version or my setup, but a design flaw when running on an automation server.
Even I am looking for this feature. We can have common report for all the test suites running in the test suite collection o r else in the pipeline it is getting very difficult to club all the individual suite reports to mark whether the build has be passed/failed.
