# Self-tests for gm, based on tools/tests/run.sh
|
|
#
|
|
# These tests are run by the Skia_PerCommit_House_Keeping bot at every commit,
|
|
# so make sure that they still pass when you make changes to gm!
|
|
#
|
|
# TODO: currently, this only passes on Linux (which is the platform that
|
|
# the housekeeper bot runs on, e.g.
|
|
# http://70.32.156.51:10117/builders/Skia_PerCommit_House_Keeping/builds/1417/steps/RunGmSelfTests/logs/stdio )
