Terraform 1.10 Test No ephemeral resource types in mock providers

Hi everyone,

it looks like using the new ephemeral resource breaks terraform test with mock providers:

tests/unit.tftest.hcl... tearing down
tests/unit.tftest.hcl... fail
Failure!╷
│ Error: No ephemeral resource types in mock providers
│ 
│   with ephemeral.aws_secretsmanager_secret_version.postgres_master_credentials,
│ The provider mocking mechanism does not yet support ephemeral resource
│ types.
╵

Is there an eta for the mock provider to support this ephemeral resource? Or any other workaround to use ephemeral in .tf-files while testing them with terraform test?

Thanks in advance!
