I'm not really sure how to test the cache persistence across versions. Looks like I would need to simulate a change in the CFBundleShortVersionString, and I don't know how to do that. @nodes-ios/developer-team any suggestions on this one?

[Dominik Hádl]

Look at how the cache compares versions. I think you should be able to manually change that in NSUserDefaults, so you could make the cache think there's new version :)

[Marius Constantinescu]

I made the change manually in NSUserDefaults, but my test failed. So I investigated a bit more and saw that [[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleShortVersionString"] is nil and [[NSBundle mainBundle] infoDictionary] is an empty dictionary.

.

[Dominik Hádl]

That is most likely because of the tests bundle. As a quick hack, swizzling the infoDictionary getter method of NSBundle with a custom implementation would work. Then you can easily control version numbers returned from your custom infoDictionary.

Made PR for Cashier tests #13. NOPersistentStore ignored for the moment

[Marius Constantinescu]

We have added some tests for NOPersistentStore in the Swift types tests. As always, tests can always be improved. But it's safe to close this issue now.
