Let's split this into separate issues for each package.

Current test status:

• integration tests
• condition functions
• processing functions - Unit tests for processing functions #30
• large converter functions like apply_mapping - Finish unit tests for converter #33
• small converter functions like crate and mapping utilities
• uploader functions - Finish unit tests for uploader #32
• tests for each mapping in mapping.json - Add tests for each mapping in mapping.json #31

The integration tests mean we have reasonably good code coverage:
