Sure, though we have no unit testing here.

As you'll work on the tokenizer, I think it would be nice to introduce
some kind of tokens dumper replacing the dmapper that would dump what
goes in the dmapper. That would possibly provide some way to isolate
whether the import problem comes from the tokenizer (specific to each
format) or the domain mapper (that would impact all handled formats).
You would then have a much more reliable way to test that your tokenizer
is working... but that wouldn't help testing the domain mapper. To test
that one, I think that mostly conversions like those you are explaining

Yes, the ODF is a pretty good representation of the internals... though
we could surely implement something nearer from the actual data
structures. Let me know if it would be of any use to create such a
dumper... I'm sure we could come pretty quickly to something useful.
