test plan:
  - create two course-level outcomes
  - create an assignment with a single question, and align the 1st outcome via a rubric
  - create a quiz bank with a single auto-gradeable question (e.g. true/false), and
    align the 2nd outcome to it
  - create a quiz that pulls the single question from the quiz bank above
  - as a student, submit to the assignment and the quiz
  - as a teacher, assess the assignment, providing a score to the rubric
  - as a teacher, confirm:
    * both outcomes have results in the LMGB
    * both outcomes have results in the sLMGB
  - as a student, confirm:
    * both outcomes have results in the sLMGB
  - as a teacher, mute the assignment in the gradebook:
    https://community.canvaslms.com/docs/DOC-12961-4152724339
  - as a teacher, confirm:
    * both outcomes have results in the LMGB
    * both outcomes have results in the sLMGB
  - as a student, confirm:
    * only the outcome associated with the quiz bank has results in the sLMGB
  - as a teacher, mute the quiz in the gradebook
  - as a teacher, confirm:
    * both outcomes have results in the LMGB
    * both outcomes have results in the sLMGB
  - as a student, confirm:
    * no outcomes should have results in the sLMGB
  - as a teacher, unmute the assignment in the gradebook
  - as a teacher, confirm:
    * both outcomes have results in the LMGB
    * both outcomes have results in the sLMGB
  - as a student, confirm:
    * only the outcome associated with the assignment has results in the sLMGB
