tests/site_tests.py::TestUsernameInUsers::test_username_in_users Password for user Pywikibot-oauth on wpbeta:en (no characters will be shown): The job exceeded the maximum time limit for jobs, and has been terminated.
Job #20 (with OAuth on test.wikpedia.org) has more than 1000 of the following warning:
WARNING: /home/travis/build/wikimedia/pywikibot-core/pywikibot/comms/http.py:345: UserWarning: Invalid authentication tokens for test.wikipedia.org set in `config.authenticate`
The failure has appeared after 4bb76aa, but I can't find any relation between that commit and the failure.
Also it only has affected jobs #15, #16, and #20. These jobs have OAUTH_DOMAIN set in their enviroment variable.
