The did tool currently does NOT show if Jira tickets are covered by a test case or a test plan, but a similar function is implemented for the Bugzilla tickets.
It would be great if the did tool showed the statistic of Jira tickets covered by tests. Here are some ideas how to find out:
Option: if the Test Link field is not empty then the Jira ticket is covered
Option: if the Test Plan field is not empty then the Jira ticket is covered
Option: if the Issue links section contains a record ‘TCMS Test Case’ then the Jira ticket it is covered
