Automate Non-functional Tests #994
Description
After completing our manual non-functional testing and documenting the process, we should proceed to automate our non-functional tests so they do not incur additional toil on the release process.
The below stories are linked to a manual non-functional test. Each test should be automated to the point where a script can be manually ran to execute the test.
