Canvas has a built in Test Student - any actions you take in Student View are attributed to Test Student. It gives you a very good picture (but not 100%) of what actual students encounter in your course.
When I work, I often add an actual Test Student to my course for troubleshooting and documentation purposes. To do that I create a free email account using gmail or yahoo or something.
