The Apply S3 Bucket Policy action can be used to apply a bucket policy to one or more S3 buckets.
This action includes a "test mode" as a way of determining which buckets will have the policy applied without actually applying the policy. This way, you can fine tune your action without concern for applying to the wrong buckets.
When test mode is enabled, execute your action normally then check the action logs to verify that only buckets that should have been modified would have been modified, and that buckets that should not have been modified would not have been modified.
When you are satisfied, disable Test Mode.
Please see Common Action Settings for a description of settings common to all action types.
