Selenium fails to connect to firefox (headless not sauce):
unable to obtain stable firefox connection in 60 seconds or
Connection refused - connect(2) (Errno::ECONNREFUSED)

| Wikidata headless browser tests: disable triggering | integration/config | master | +0 -2 |
To make this work: try to do the same as the gerrit triggered build, see mw-set-env-mw-selenium.sh in jenkins repo.
Should double check the XVFB display vary by executor just like mw-set-env-mw-selenium.sh
So we should verify we use something like:
# Let MW-Selenium setup/teardown an isolated Xvfb on a display between 70-90 # for this build export HEADLESS=true export HEADLESS_DISPLAY=$((70 + EXECUTOR_NUMBER % 20)) export HEADLESS_DESTROY_AT_EXIT=true export HEADLESS_CAPTURE_PATH="$WORKSPACE/log"
Our jjb macro browsertest-website only does HEADLESS=true :-(
Change 252234 had a related patch set uploaded (by JanZerebecki):
Wikidata headless browser tests: disable triggering
Change 252234 merged by jenkins-bot:
Wikidata headless browser tests: disable triggering
The problem in the Wikimedia CI still exists. We just disabled using the headless jobs.
Unlikely to ever be resolved because of T139740: Port Selenium tests from Ruby to Node.js.
