Change Details

At Lyon we decided that before setting up automated testing against an empty test instance, we should first run the tests against a empty test instance set up on wmflabs. https://tools.wmflabs.org/pywikibot-testwiki/ was created for this purpose, and the Pywikibot-test account was created on that instance with the standard password for that account. Permission to create accounts is not enabled, to prevent spam. However this means that Travis builds not using the 'wikimedia' github account, and thus the Pywikibot-test wiki account, cant access the wiki. We will need to alter the test system to support the user tests only for the 'wikimedia' github account, possibly by detecting that a configured test username is not present on the wiki.
