I'm not saying using libcurl directly is wrong, but Privoxy (HTTP proxy)
is mainly tested with privoxy-regression-test which is a Perl script that
calls curl:
(Scroll down to see the perldoc documentation)

While privoxy-regression-test is written to test Privoxy,
it does not require Privoxy to work and some of it's tests can
also be used to verify the behaviour of other proxies and webservers
(for example to confirm that redirects work as expected).

curl obviously doesn't expose all libcurl features, but for Privoxy's
purposes it works rather well. To further increase the test coverage I
started to leverage curl's test suite, but so far trying to upstream
the required patches has failed.
