Description of proposed changes

Practical tips for PR review & merge:

  • All GitHub Actions report PASS
  • Newly added code/functions have unit tests
    • Coverage tools report all newly added lines as covered
    • The positive scenario is exercised
    • Negative scenarios are exercised, e.g. assert on all possible errors
    • Assert on events triggered if applicable
    • Assert on changes made to storage if applicable
  • Modified behavior/functions - try to make sure above test items are covered
  • Integration tests are added if applicable/needed
