# Description
|
|
# -----------
|
|
# Command line interface for the GUT unit testing tool. Allows you to run tests
|
|
# from the command line instead of running a scene. Place this script along with
|
|
# gut.gd into your scripts directory at the root of your project. Once there you
|
|
# can run this script (from the root of your project) using the following command:
|
|
# godot -s -d test/gut/gut_cmdln.gd
|
|
#
|
|
# See the readme for a list of options and examples. You can also use the -gh
|
|
# option to get more information about how to use the command line interface.
|
|
#
|
|
# Version 6.7.0
