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-43630920-8b3a-11eb-ad16-f1ef4faaa8ce"]`, but never found it.

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

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