I don't recall seeing a release that would enable us to identify stories that do not have any linked cases, but you can check with SmartBear Support for a definitive answer.
However, just in case they also say it's not possible, I may have found a way to work around that problem.
Assumption: your test cases are in a test cycle. If you've created ad-hoc test cases, they will not be in a test cycle and you will need to ensure they are added into at least 1 test cycle - this is because reports need an execution record and placing a test case into a test cycle automatically creates a Not Executed test execution record
- Go to Reports and select report "Test execution results (list)"
- Select your Project
- Choose Advanced Filtering
- Expand Test Case
- Select "Linked Issues"
- Choose the "Not In" option, and
- Select two Story issues - you can't type them in so we will just select two for now
- Hit the Generate button
- Copy the URL of the report into a text editor
- Find the Story you added into the criteria. It will look something like this: testCase.issueKey%20IN%20(%22KEY-1%22%2C%20%22KEY-2%22)
- You now have the text version of how to generate the report, and how to add multiple Stories as criteria
- Next step is to create your new criteria that includes all Stories, and then replace the criteria in the report and run
- In theory this should work
Please let me know if this works for you?
