xclip - how to use without a graphics display for testing on Github workflows

[Tom Browder <tom.browder@gmail.com>]

We have a Raku module that uses "xclip" during use on a computer with a monitor.  We need to test it with Github workflows which does not have a graphics device.

Is there any "xclip" option to allow for testing without a graphics devivce without throwing an error? Or any suggestion for a work around?

Thanks.
