iOS Testing Resource

I am looking for a single resource (book, website, videos, code, etc) that covers testing iOS 9 on Xcode 7. I would like it to cover testing codedata, nsurlsessions, asynchronous code, mocking and stubbing, and ui testing.

I have found it difficult to find an consistent approach using multiple resources while the more inclusive resources I have found seem very outdated. Apple's doc are great but they don't really offer a high level approach or discuss external tools.

Any guidance or direction would be highly appreciated.

Thanks all
