'parse raises an error for unknown switches' test failure

Hello,

Updating this package to 1.2.1 in GNU Guix, I see the following test failure:

starting phase `check'

The direct dependencies in use are:

Perhaps something to do with the very recent rspec version used?

Thanks!

Which version of Ruby are you using?

I think it was 2.7.x.
