Possibly related:

To execute unit tests you need to set up the environment variable 'SINGLESTORE_LICENSE' with SingleStore license value.
To get a free-tier license you need to create a free SingleStore account.

Related or otherwise, this makes me queasy. Executing the tests for this open source project should not require a license.
