Review Comment:
Hm, I guess so. As `file_path` is a URI and you are reading from direct
path, you are also checking that the filesystem is selected correctly.
When thinking about it I wondered if it would be good to also add a test
with supplying a `filesystem=fs.LocalFileSystem()` to `read_metadata` and
`read_schema` (or maybe some other to catch an error)?
