Test harness to show handling of invalid inputs

[yurishkuro]

I may be missing something, but should the test harness (https://github.com/w3c/baggage/blob/main/test/test_baggage.py) contain examples of invalid inputs and how to handle them? Right now it only seems to include well-formed inputs.

Thanks for raising this issue.

We discussed this in one of the recent working group meetings:

As discussed in #137, the behavior for handling invalid baggage entries is undefined. So, we don't think the test harness needs to handle it.
