The areas we seem to be missing code coverage:
- PoolCounter (https://wikitech.wikimedia.org/wiki/Thumbor#Poolcounter-based; code wikimedia_thumbor/poolcounter/__init__.py)
- Swift (code wikimedia_thumbor/loader/swift/__init__.py, wikimedia_thumbor/result_storage/swift/swift.py)
- Error/exception handling
- Several files in wikimedia_thumbor/logging/
- Several files in wikimedia_thumbor/error_handlers/
- wikimedia_thumbor/storage/request/request.py (not sure what this does)
- wikimedia_thumbor/core/importer.py (not sure what this does)
- wikimedia_thumbor/core/context_importer.py (not sure what this does)
Testing PoolCounter and Swift might not be possible without getting these services running locally. This might be hard, particularly with Swift.
