We are using JIRA and have Testrail integration enabled.
Our current implementation does not use "sprint bugs" (subtasks on the stories), but rather only issuetype = bugs. I've been told this is because Testrail cannot handle subtasks. I've done some light reading here but I haven't found a definitive answer. I'd like confirmation that Testrail does not handle subtasks on JIRA stories.
I've found a partial answer.
(Yes, it's overall possible.)
However, the question in the following post makes me wonder if there's a negative impact on Testrail reporting.
So it would still be great if someone more knowledgeable weighed in.
