I had a deeper look. I tried to convert the test suite to using Rack3
(and rackup). I pushed my changes to branch 'rack3'.
But then I run into the following test failures:
1) Ethon::Easy::Http::Custom#setup when body when multipart when requesting
submits a body
Failure/Error: expect(easy.response_body).to match('"body":".+"')
expected
