I guess you can technically test everything in a CRUD app as integration test. Doesn't mean you should. Surely, you have a baseline of verification/validation logic for which unit tests are the best fit. And based on my experience of my last project, if you can't do proper unit testing you likely have the wrong granularity in your methods and classes.
