Missing References and Error Handling in Test Runner
References between test steps can be broken for the following reasons:
• The source referencing test step is referencing an original test step that no longer exists.
• The source referencing test step is referencing an original test step that does exist, but the current user has no permission to view it.
In both the cases, the test case editor and the item details page notify the user about the situation.
The broken reference can be fixed by editing the test case or correcting the permissions.
If one of these errors happen during a test run, the test runner displays an error message.
