Unit tests were not running by default in Minerva - only when you run check experimental does Jenkins bother to run them. This is being fixed in T181429.
Some how a unit test got broken and is blocking merges elsewhere.
- 2 unit tests are breaking and relate to the NotificationBadge due to incorrect usage of NotificationBadge
- An option used by the test notificationCountRaw is not used.
- Options names used in test are wrong - notificationCountString and notificationCountRaw NOT notificationCountRawString and notificationCountRawRaw
- notification-count data attribute is not present on other unit test
Probably broken unwittingly in T172755.
I submitted a (WIP-ish, unmerged) patchset against RelatedArticles but jerkins is downvoting it consistently; it seemed to me that the failure was entirely unrelated to my patch, which was confirmed my @Legoktm's test patch against RelatedArticle's README file, which obviously in no way could have caused the tests to fail.
