Question

Is there any Jira API which can give me info about the linked TCs or count of linked test cases to a specific defect. Qtest (TC mgmt toold is integrated with Jira)

I am using below api and I checked issuelinks field but its giving me high level test case project details not not test case/test run info.

Hi @Gurpreet Singh ,

It appears you are trying to get information about test cases that are linked to an issue, the thing is that probably this test cases issue types were made through a plugin, such as Testrails, Xray or Zephyr.

If so, these apps have their own API endpoints to get the data.  Can you check on your end and let me know if this is the case, and which plugin is?

Thanks,
David
