Currently, if the credentials to the secret manager are not set correctly, the tests end up throwing exception like this -
MFTF uses Credential Storage in the following precedence: .credentials file, HashiCorp Vault and AWS Secret Manager. You need to configure at least one to use _CREDS in tests. And make sure key/value exists.
Not sure why it doesn't throw this error instead - Unable to create AWS Secret Manager client

eg: CREDENTIAL_AWS_SECRET_MANAGER_PROFILE=asdf (not existant)
CREDENTIAL_AWS_SECRET_MANAGER_REGION=us-east-2 (non existant)

One more thing, There is no error if you use non-existing profile when create AWS client. There will be error when access the secret. Thus the generic error message.

Since the CI/CD story may end up changing the order will it be better to modify the exception message to - You need to configure atleast one of these options: .credentials file, HashiCorp Vault or AWS Secrets Manager correctly and ensure key, value exists to use _CREDS in tests.

Implementation looks good. Needs branch update + a build trigger just to triple check
