Dear Chris,

#702 will add the CI setup and GHA, and it looks like you like it. As a followup, this patch will consecutively remove Travis CI, and tox.

With kind regards,
Andreas.

I saw your reference that we shouldn't be even using codecov anymore as well. Great investigation on your part.

I"m okay with merging this now or if you think we should drop codecov here too and add it to the github actions too? I seem to think this comment may be dejavu and already addressed though. You've been a machine with all the amazing work you've done over the past few weeks. Is that the case here?

Are you referring to the codecov-python program here? Yeah, it is getting deprecated, see codecov/codecov-python#198 (comment).

Code coverage reports are being uploaded using the Codecov Action already, as recommended.
