In fact, players on Bethesda’s own forums are also requesting a test server, “Hey dear Bethesdateam, i know you create these wonderful bug fixes and other content patches and testing them on your own. But we, the community got a lot of time and we are more people with different builds and interests. We could find more bugs and other broken stuff in less time. Give us a chance to be a bigger part in this game and let us work togather and test these patches with you before it hits the live-servers. After every patch the community finds a lot of “broken” stuff in just a few minutes / hours. We could prevent those things.”
