• In a plugin like pearson-core, add a openedx-events receiver for the signal openedx_events.learning.signals.COURSE_PASSING_STATUS_UPDATED.
• Configure grading for a course.
• Verify that when the score of a learner is updated the signal receiver is triggered.
• Repeat but now with openedx_events.learning.signals.CCX_COURSE_PASSING_STATUS_UPDATED.
