[tishin-endou]

Unit tests (under tests/providers/azureblob/):

Listing (including pagination)
Metadata for file / folder / root
upload / download / delete / move / copy
Error paths (e.g., 404, 401/403, 409, etc.)
Fixtures: a comprehensive set of mocked Azure REST (XML) responses
Contract test: subclass ProviderTestCase to verify the implementation satisfies the common provider interface used by existing providers.
