# ##############################################################################
# This class joins together GUT, GUT Gui, GutConfig and is the main way to
# run a test suite.
#
# This creates its own instance of gut.gd that it manages.
# Use set_gut_config to set the gut_config.gd that should be used to configure
# gut.
# This will create a GUI and wire it up and apply gut_config.gd options.
#
# Running tests:
# By default, this will run tests once this control has been added to the tree.
# You can override this by setting ran_from_editor to false before adding
# this to the tree.  To run tests manually, call run_tests.
