Is your feature request related to a problem? Please describe.
Likely related to random number use in unit tests (#228

Failed coverage here: https://github.com/skliper/CF/runs/6581159060?check_suite_focus=true

Overall coverage rate:
  lines......: 99.9% (2678 of 2681 lines)

Note it passed in the very next run w/ no code changes (was just a requirements update)

Describe the solution you'd like
Remove whatever random test implementation is causing this (all others eventually to fix #86)

Describe alternatives you've considered
None

Additional context
#86
