If I'm paying for a Cockroach Cloud cluster (managed CockroachDB), I can run tests for my application without spending money by running them against a temporary cockroachdb instance I start up myself. But if my test requires an enterprise feature (e.g. it involves a changefeed to an external sink), I'm out of luck as I don't have a license key. Is there any way to do this without mocking out the database entirely?
