Mahmood Ali d2ef657abc api: test api and structs are in sync
Add some tests to ensure that api/structs values are in sync.

Given that vendoring libraries prune tests by default, test dependencies
aren't leaked to clients of the package - so it should be safe to add
such dependency without affecting api clients.
