expectations/gm/ignored-tests.txt

 # Failures of any GM tests listed in this file will be ignored, as if they
 # had been marked "ignore-failure": true in the per-builder
 # expected-results.json files.
 #
 # The idea is that, if you modify a GM test in such a way that you know it will
 # require rebaselines on multiple platforms, you should add that test's name to
 # this list within the same CL that modifies the test.
 # Then, AS SOON AS POSSIBLE, you should rebaseline the tests (they will show up
 # as status "failure-ignored") and remove the line you added to this file.
 # If there are any lingering failures that need to be suppressed (ignored), you
 # MUST move those suppressions into the per-builder expected-results.json files.
 #
 # Any lines starting with '#' are comments and will be ignored.
 # Other than that, each line must either be whitespace or list just one test.
 #
 # For more information, see https://code.google.com/p/skia/issues/detail?id=1600
 # ('GM expectations: create tool to suppress failures until new baselines are
 # checked in')
 
 # EXAMPLE: (remove the first '#' on each line)
