This is making flymake-tests fail:

    Test different-diagnostic-types condition:
        (ert-test-failed
         ((should
           (eq 'flymake-error
                (face-at-point)))
          :form
          (eq flymake-error flymake-note)
          :value nil))
       FAILED  1/9  different-diagnostic-types (1.093461 sec)

(face-at-point) is flymake-note there.
