There are no flaky tests on this bot now, and if we introduce any, we should be told about that in RED.
Created attachment 212827 [details] proposed patch There is a potential downside to this change - run-webkit-tests forces pixel testing when retrying, so it provides pixel results for tests that failed both times. But forcing pixel tests changes a lot anyway, so I'm not sure if those pixel results were more useful or misleading.
Comment on attachment 212827 [details] proposed patch Looks fine except for the obvious typo: --no-retry-faiures. Please fix that before landing.
