The FTP server in the curl test suite is in fact also a IMAP, SMTP and POP3
test server. It follows the same tradition as the HTTP server there: they are
as stupid as possible so that the test case clearly tells it what to respond
to the particular requests that the test case entails.

So, if test 1 would return a directory listing, then test 1 will tell the FTP
server exactly how that would look. That makes it very easy to make the server
respond in very weird ways that may be non-compliant or whatever - at will.

That's basically how we do all the test cases in curl, and that's why I don't
consider using a "standard" server for doing protocol tests since such servers
are designed to actually always adhere to the protocols in question.

But lastly, does pycurl really need to double-check the actual underlying
protocol implementation? You'd basically only be verifying that the existing
curl test suite is good enough, for no particular extra value.

I would say that you should rather make an effort to make sure that a certain
set of pycurl code gets translated into a certain chain of libcurl calls. But
maybe that's just how I view things...
