- Issue #17944: test_zipfile now discoverable and uses subclassing to
generate tests for different compression types. Fixed a bug with skipping
some tests due to use of exhausted iterators.
- Issue #18266: test_largefile now works with unittest test discovery and
supports running only selected tests. Patch by Zachary Ware.
