This was supposed to have un-flaked the tests: https://gerrit.wikimedia.org/r/c/mediawiki/extensions/Cite/+/991532

It's fine to skip them, if they're still broken of course.

I've confirmed that the tests are still flaky, affecting patch https://gerrit.wikimedia.org/r/c/mediawiki/skins/MinervaNeue/+/993808 . CI had checked out the master branch of Cite which included the improvements to avoid race conditions.

It seems there is another race condition to guard against, but I don't fully understand yet. This time the failure was while loading the newly-created test page:

00:06:37.108   1) Cite backlinks test
00:06:37.108        "before each" hook for "hides clickable up arrow by default when there are multiple backlinks":
00:06:37.108      CypressError: `cy.visit()` failed trying to load:
00:06:37.108 
00:06:37.108 http://127.0.0.1:9413/index.php?title=CiteTest-title0.27191064498966355
00:06:37.108 
00:06:37.109 The response we received from your web server was:
00:06:37.126 
00:06:37.126   > 404: Not Found
00:06:37.126 
00:06:37.126 This was considered a failure because the status code was not `2xx`.

00:06:37.137   From Your Spec Code:
00:06:37.137       at Context.eval (webpack://Cite/./cypress/e2e/tests/backlinks.cy.js:29:5)

The video shows that the page doesn't load at all--it's not the MediaWiki 404 page.

Update: the 404 page is being intercepted at some level so getting the default browser 404 is unsurprising. My current theory is that the page is not fully created so I've added an await and an assertion on the API response.

Change 994010 had a related patch set uploaded (by Awight; author: Awight):

Change 994010 merged by jenkins-bot:

should be fixed now. the team will keep an eye on the tests for some more days though.
