This interface defines pure-virtual methods for each of the user-facing overload sets in Client. That is, all of Client's Read() overloads will forward to the one pure-virtual Read() method declared in this interface, and similar for Client's other methods. This allows users to inject custom behavior (e.g., with a Google Mock object) in a Client object for use in their own tests.
To create a concrete instance that connects you to a real Spanner database, see MakeConnection().
