+"""Tests for gsutil naming logic.
+The test code in this file runs against an in-memory storage service mock,
+so runs very quickly. This is valuable for testing changes that impact the
+naming rules, since those rules are complex and it's useful to be able to
+make small incremental changes and rerun the tests frequently. Additional
+end-to-end tests (which send traffic to the production Google Cloud Storage
+service) are available via the gsutil test command.
