Undefined property: stdClass::$gradepointdefault when initialising PHPUnit

On Moodle 3.0+ (Build: 20151209), version 2015111600.04 if you initialise PHPUnit (on Windows) with:

php admin\tool\phpunit\cli\init.php

then you get the following error:

PHP Notice:  Undefined property: stdClass::$gradepointdefault in F:\moodledev\moodle30\lib\grade\grade_item.php on line 270

looking at the line it has:

self::set_properties($this, array('grademax' => $CFG->gradepointdefault));

This is not defined in the $CFG global or is it mentioned in config-dist.php. If it would is auto generated when installing then for those who upgrade and copy their config.php file there is no indication about adding it.
