How can these scenarios related to Octokit be checked in Rspec

I am trying to cover these exceptions raised by Octokit when something undesired happens. These are some of the scenarios that needs to be covered in my spec, however I am not getting any relevant tests to refer for this: Octokit::AbuseDetected

Octokit::UnprocessableEntity

Octokit::TooManyRequests

Also I am finding no related resources for the same. This is the file that has these.

The method retry_on_abuse handles these scenarios. How do I write specs for these?
