Hello Mitch,
Ideally. production is not meant for testing. Every testing has to happen in lower environments and the change/functionality needs to promoted to PROD.
My suggestion would be to refresh the PROD data in the lower environment immediately and perform the testing.
If you still want to have a testing in the PROD, You may have the dedicated org/site created for testing, so that it won't impact the working org/sites. Request to keep the test records creation limited in PROD.
