21 : /// First, the test creates a set of S3 objects with keys `/${random_prefix_part}/${base_prefix_str}/sub_prefix_${i}/blob_${i}` in [`upload_remote_data`]
22 : /// where
23 : /// * `random_prefix_part` is set for the entire S3 client during the S3 client creation in [`create_s3_client`], to avoid multiple test runs interference
24 : /// * `base_prefix_str` is a common prefix to use in the client requests: we would want to ensure that the client is able to list nested prefixes inside the bucket
25 : ///
26 : /// Then, verifies that the client does return correct prefixes when queried:
27 : /// * with no prefix, it lists everything after its `${random_prefix_part}/` — that should be `${base_prefix_str}` value only
28 : /// * with `${base_prefix_str}/` prefix, it lists every `sub_prefix_${i}`
29 : ///
30 : /// With the real S3 enabled and `#[cfg(test)]` Rust configuration used, the S3 client test adds a `max-keys` param to limit the response keys.
31 : /// This way, we are able to test the pagination implicitly, by ensuring all results are returned from the remote storage and avoid uploading too many blobs to S3,
32 : /// since current default AWS S3 pagination limit is 1000.
33 : /// (see https://docs.aws.amazon.com/AmazonS3/latest/API/API_ListObjectsV2.html#API_ListObjectsV2_RequestSyntax)
34 : ///
35 : /// Lastly, the test attempts to clean up and remove all uploaded S3 files.
36 : /// If any errors appear during the clean up, they get logged, but the test is not failed or stopped until clean up is finished.
