Does iCloud have some kind of developer mode?

I'm developing a photos extension application. Sometimes the users photos can be local on disk and sometimes they have to be fetched over network from iCloud. Testing the application under the 'fetch from iCloud' conditioin is tedious, delete all local photos-> upload new batch to icloud -> sync with iCloud. Does iCloud maybe have a developer mode to avoid these steps?
