The DSN must be given in the following format.

spanner://projects/{projectId}/instances/{instanceId}/databases/{databaseName}

See Google Spanner Documentation for details.

Param WithInstance Config Description
x-migrations-table MigrationsTable Name of the migrations table
url DatabaseName The full path to the Spanner database resource. If provided as part of Config it must not contain a scheme or query string to match the format projects/{projectId}/instances/{instanceId}/databases/{databaseName}
projectId The Google Cloud Platform project id

Testing

To unit test the spanner driver, SPANNER_DATABASE needs to be set. You'll need to sign-up to Google Cloud Platform (GCP) and have a running Spanner instance since it is not possible to run Google Spanner outside GCP.
