from the use of the tool we learned, that TC user assigment expires after 24 hours and the TC has to be reassigned. Is there a way to change the period of the TC assigment?
Thank you for posting! TestRail should not automatically change or remove the user assignment of a test after 24 hours (or after any other specified time period) and tests should remain assigned to users until they are manually reassigned to preserve an audit trail. You can review the user assignment history of an individual test in the results & comments section of the test overview page to see which user has changed the user assignment. If you are still unsure or are experiencing issues with this, please send us a screenshot of the results & comments section of a test that is exhibiting this behavior.
I hope this helps!
