Also, this one should have an integration test. Let me know if you need help with that.

Sure. Thanks. 👍

Also, this one should have an integration test. Let me know if you need help with that.

I modified an existing test in packages/@aws-cdk-testing/framework-integ/test/aws-rds/test/integ.cluster.ts.
