# This is the list of tests to run. It is a dictionary with the following
# fields:
#
# name (required): The name of the step, to show on the buildbot status page.
# path (required): The path to the executable which runs the tests.
# additional_args (optional): An array of optional arguments.
# uses_app_engine_sdk (optional): True if app engine SDK must be in PYTHONPATH.
# uses_sandbox_env (optional): True if CHROME_DEVEL_SANDBOX must be in
#   environment.
# disabled (optional): List of platforms the test is disabled on. May contain
#   'win', 'mac', or 'linux'.
# outputs_presentation_json (optional): If True, pass in --presentation-json
#   argument to the test executable to allow it to update the buildbot status
#   page. More details here:
