Since bug 72056 was fixed, mediawiki_api 0.3.0 reports HTTP failures, yay. AFAICT, to bask in the nicer error reporting, someone has to:
cd extensions/SomeExtension/tests/browser bundle update git commit -m 'QA: Bundle update for latest mediawiki_api' Gemfile.lock git review
The 12 extensions using mediawiki_api appear to be:
CentralAuth
CirrusSearch
ContentTranslation
Echo
Flow
GettingStarted
Math
MobileFrontend
MultimediaViewer
UploadWizard
WikiLove
ZeroPortal
gerrit 166866 is the change for Echo.
Version: unspecified
Severity: normal
