Test Failures

Kibana Pipeline / general / "before all" hook for "should contain notes".Timeline notes tab "before all" hook for "should contain notes"

Link to Jenkins

Stack Trace

Failed Tests Reporter:
  - Test has not failed recently on tracked branches

AssertionError: Timed out retrying after 60000ms: Expected to find element: `[data-test-subj="title-1f6092a0-70e0-11eb-8e36-dbbba9c4a1b1"]`, but never found it.

Because this error occurred during a `before all` hook we are skipping the remaining tests in the current suite: `Timeline notes tab`

Although you have test retries enabled, we do not retry tests when `before all` or `after all` hooks fail
