What is the output of python pwb.py version?

family and mylang are not set.
Defaulting to family='test' and mylang='test'.

It's more-or-lest recent git, with the patch from https://gerrit.wikimedia.org/r/542456 on top.

The error message is not clear, but it seems to me Pywikibot can not detect wiki API at the url given. MWSite should change to Site immediately after MediaWiki API is found, thus lang should work correctly after that, which it doesn't. What MW version does your wiki use?

Or wiki API has been detected, but Pywikibot can not read from API somehow. Anyway this only happens with your patch, I hope this is the issue of yout implementation then.

And I agree with @zhuyifei1999, you should save the login credentials to your OS connection config and not deal with them inside Pywikibot's code, at least not this way at this place on every fetch. This just doesn't look right to me and I'm not much surprised it does not actually work.

@Dvorapa, change 542456 is unrelated to this failure, I can reproduce this failure with unmodified PyWikibot.

I've uploaded an updated fix for this task, change 543107, with a testcase:

nosetests-3 -v tests.site_detect_tests.PrivateWikiTestCase

You can revert the fix and watch the test fail :)
