If test fail it will print out non-telling message which make debugging a little bit hard:

 FAIL: test__https_verify_envvar (test.test_ssl.ContextTests)

Would be possible to change following code which is being executed:

+        https_is_verified = """import ssl, sys;\
+            sys.exit(ssl._create_default_https_context is not
+                     ssl.create_default_context)"""

into something like

https_is_verified = """import ssl, sys;\
value = ssl._create_default_https_context is not ssl.create_default_context;\
sys.exit('ssl._create_default_https_context should be set to verified' if value else value)"""

So traceback will look like this:
...
    "stderr follows:\n%s" % (rc, err.decode('ascii', 'ignore')))
AssertionError: Process return code is 1, stderr follows:
ssl._create_default_https_context should be set to verified
