Should this really be in the non-test code? Since it's only used by unit tests and does spin up an ephemeral container in the Postgres case?

Good point re test code vs non test code. I'd need to double check, but I don't think an init is run in a _test.go when a package is imported.

Re postgres container: this'll only happen if the New method of the driver is called (won't be created unconditionally).

driver := mssmt.TreeStoreDriver{
Name: activeTestDB,
New: func(args ...interface{}) (mssmt.TreeStore, error) {
dbPath, ok := args[0].(string)
if !ok {
return nil, fmt.Errorf("invalid db path: "+
"want string, got %T", args[0])
}
namespace, ok := args[1].(string)
if !ok {
return nil, fmt.Errorf("invalid db path: "+
"want string, got %T", args[0])
}

sqlDB, err := NewDbHandleFromPath(dbPath)
if err != nil {
return nil, err
}

txCreator := func(tx *sql.Tx) TreeStore {
return sqlDB.WithTx(tx)
}

treeDB := NewTransactionExecutor(sqlDB, txCreator)

return NewTaprootAssetTreeStore(treeDB, namespace), nil
},
}
if err := mssmt.RegisterTreeStore(&driver); err != nil {
panic(fmt.Errorf("failed to register db=%v): %v",
activeTestDB, err))
}
}
