Has anyone used ActionController::Integration::Session#post in their
integration tests to post multipart/form-data encoded parameters?
my_session.post url , encoded_string , headers
where 'headers' includes the content-type and content-length.
Is there a library which will help generate this encoded string in ruby?
eg Net::HTTP::Post or something in rails?
I've started looking at RFC 2046, and various fragments people have
posted in the past - but I live in hope.
