In the “JUnit_Report.xml” file that is produced when a Test Suite runs, please add a “Description” element to each “testcase” element. I see there the overall test case info, is reported in the “testsuites” , “Time” and “testcase” elements, but it is missing from each “Description” element.
Custom Report uses this Description element to report, having meta data for each test case while run, thus it shows that all tests data while parallel execution.
Thank you!
