TST: Streaming of S3 files
State: closed

Issue #17135 was resolved by an upstream change, this is just a unit test to avoid regressions.

Labels:
name: Testing
description: pandas testing functions or related to the test suite
name: IO Data
description: IO issues that don't fit into a more specific label

Comments:
CI will crash and burn as I didn't add `botocore` as a dependency properly. Any help on this appreciated.
I think the easiest thing to do is to ensure the test is skipped without botocore, and rely on `s3fs` pulling it in as a dependency.
