#testing - Usually refers to testing a system as a whole, involving all layers of an application (e.g. all the way from the UI to the database and back) - I consider this is a good term when used as adjective ("we are testing something end-to-end"), but a superfluous and even confusing term if used for a test level. This is because there are already two concisely named [[Test levels]] in place where tests are touching the application end-to-end: [[Test levels#System testing|system testing]] and [[Test levels#Acceptance testing|acceptance testing]]
