The public cyrus.andrew.cmu.edu IMAP server (port 993) doesn't accept TLS connection using our self-signed x509 certificate. The following two tests of test_imaplib were skipped by the issue #30175:

* test_logincapa_with_client_certfile() of RemoteIMAP_SSLTest
* test_logincapa_with_client_ssl_context() of RemoteIMAP_SSLTest

We should either remove these tests or spawn an IMAP server which accepts such certificate on pythontest.net.

@Benjamin: Is there someone available to build such IMAP server on pythontest.net? Or do you suggest to just remove the 2 unit tests?

I can't say I'm very interested in running a imap server. It would be best if these tests could be replaced by something local. Failing that, I suppose we'll have to remove them.

Is there someone interested to write such local IMAP server to test test_imaplib using a client x509 certificate?

> Failing that, I suppose we'll have to remove them.

That's not my favorite option, but I wrote a patch for that:
https://github.com/python/cpython/pull/1419

If no one speak up to propose a fix for the two skipped tests before a deadline of two weeks, I will removed them, apply:
https://github.com/python/cpython/pull/1419

I'd suggest marking them with @unittest.expectedFailure as an alternative way to move forward.

I don't understand the purpose of tests known to fail. Is it to validate that we have bugs? :)

More or less, yes. Since the problem is not in the library code and the tests are not completely useless, using @unittest.expectedFailure might be a better short term solution than skipping or removing them (at least we are not going to forget them :))

Yet another alternative is to tweak test_logincapa_with_client_certfile to just check for DeprecationWarning. See https://github.com/python/cpython/pull/1419/files#r115050499 for details.
