Checking for "does not produce a warning" this way seems very brittle, but I couldn't see a better way from looking at https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.assertions.Annotations.html.

Guidance welcomed.

Exemption Request

This fix only changes what warnings are generated, so no changes to integration tests or snapshots required.

Appears that the warnings don't get cleared from the shared stack after each run. This could invalidate some of the other tests in this file, but I decided to just fix it for my new tests, which fail without it.

Was literally just working on this with the exact same solution and tests. LGTM! We should indeed move all the other unit tests to use their own unique stack as well.

I'm not sure how can I disable this warning ? I'm using SDK v3 and I don't know how to disable the warning :\
