### Rationale for this change The recursive selector branch for the fsspec S3 backend evaluated `len(infos) == 4` without asserting the result. As a result, an incorrect number of returned entries could pass the test unnoticed. ### What changes are included in this PR? - Assert that the recursive s3fs selector returns four entries. Fixes #50665. ### Are these changes tested? Yes. The modified test file passes Python syntax compilation, and `git diff --check` passes. The focused runtime test could not run locally because this checkout does not have the pyarrow test dependencies installed. ### Are there any user-facing changes? No. This change only strengthens an existing Python filesystem test. * GitHub Issue: #50665 -- This is an automated message from the Apache Git Service.
