@raviks789 I remember that we found an issue which we didn't fix at the time this got introduced. I found this test in my stash. Is this nonsense or do you see what this is supposed to test?

If I remember correctly, the case was if a navigation item already exists in icingadb-host-action but is not a shared item and the same navigation item is present in host-action as shared item, then only the filter needs to be transformed, instead of creating a new shared navigation item for icingadb-host-action. If I am understanding correctly the test is written for this case.

So I think this is a valid test case if the bug gets fixed.
