 This recipe can be used by components like v8 to verify blink tests with a
 low false positive rate. Similar to a trybot, this recipe compares test
 failures from a build with a current component revision with test failures
 from a build with a pinned component revision.
 
 Summary of the recipe flow:
 1. Sync chromium to HEAD
 2. Sync blink to HEAD
 3. Sync component X to revision Y
 4. Run blink tests
 -> In case of failures:
 5. Sync chromium to same revision as 1
 6. Sync blink to same revision as 2
 7. Sync component X to pinned revision from DEPS file
 8. Run blink tests
 -> If failures in 4 don't happen in 8, then revision Y reveals a problem not
    present in the pinned revision
 
 Revision Y will be the revision property as provided by buildbot or HEAD (i.e.
 in a forced build with no revision provided).
