Is it correct to assume these are temporary? I imagine in theory at least we'd want to not have this here -- most users shouldn't be passing/working in 2015 edition locally I imagine. Or, at least, we'd want tests for both.

Anyway, not a concern that needs to be resolved in this PR I think.

Yes these are temporary until the 2018 edition has hit the stable channel, and then we can change these tests back.
