Unit and end-to-end tests
This library should be thoroughly tested.

As we'd discussed @simon360, you'd made a start on this. Do you want to continue to own soley or could we break this down into smaller tasks then I can help?
Happy for any help!
Rather than overthink it, might be worth doing PRs file-by-file. Otherwise, we could spend a lot of time writing issues for each category of test that we want.
