WebDAV workarounds are isolated (based on the information obtained
from the useragent string). But a unit test is not sufficient because
it covers only a small part of the interaction between WebDAV clients
and Zope. A series of requests/replies can hardly covered by a unit test.
Tools like OpenSTA are more supposed for such purposes.
