Alicloud Storage Oss Ossutil Test

A minimal test suite for verifying your Alibaba Cloud OSS setup works before you build anything serious on top of it. It checks that your access keys and region configuration are correct, then runs through the basic OSS operations: listing buckets, uploading files, and downloading them back. You'll need credentials already configured (environment variables or the credentials file) and a bucket with read/write permissions. Think of it as a quick smoke test to catch configuration problems early, especially useful if you're setting up OSS integration for the first time or troubleshooting access issues. The tests are intentionally minimal, which is exactly what you want for a sanity check.
