What the _pk_testcookie cookie does

Cookie is created and should be then directly deleted (used to check whether the visitor’s browser supports cookies)

The name ends in a part that changes from visitor to visitor or site to site, so this entry covers every cookie whose name starts with _pk_testcookie.

Who sets it
