Simplytest.me – where to upload testing dummy patches?

Hi

Simplytest.me tool requires for all patches links to be hosted at drupal.org

“The patch URL must be from http://www.drupal.org/files/.”

I would like to upload some self-created patches just to test them online at simplytest.me for my personal teaching purposes – testing my new Git and Drupal 8 skills. However, I would not like to spam any valid Drupal issue with my dummy patches.

What would be the proper place at drupal.org to upload such personal dummy testing patches? I can see that forum posts do not allow files upload. Any other drupal.org place where such file uploads are permitted and where such patches would be ok to upload?

Kindly advice. Thank you.
