For the Core Data stack in my project's test target, I have the NSPersistentStoreDescription's url set to "/dev/null" as recommended by Apple at WWDC18. I previously was using an in-memory persistent store.
I have found that tests that test fetches where the fetch request is set to have the result type as NSFetchRequestResultType.dictionaryResultType will always fail. However, when running the project, the very same code will work as expected.
Is there really no way to test these fetches? I have found nothing from search engines.
I understand that a persistent store is required for this result type but is "/dev/null" not supposed to give us the same behaviour?
