(#h75wtqq) @lyse@lyse.isobeef.org OK. So how I have worked things like this out is to have the interface in the root package from the implementations. The interface doesn’t need to be tested since it’s just a contract. The implementations don’t need to import storage.Storage

• storage/ defines the Storage interface (no tests!)
  
  • storage/sqlite for the sqlite implementation tests for sqlite directly
    
  • storage/ram for the ram implementation and tests for RAM directly
    
• controller/ can now import both storage and the implementation as needed.
  

So now I am guessing you wanted the RAM test for testing queries against sqlite and have it return some query response?

For that I usually would register a driver for SQL that emulates sqlite. Then it’s just a matter of passing the connection string to open the registered driver on setup.
