why not jump right into webtest?
http://pythonpaste.org/webtest/ It adds yet another requirement but this is the next generation of
paste.fixture so it will be better maintained and already offers some
nicer features plus an even more pythonic interface. One nicety is
how it integrates with lxml.html to provide xpath and other useful
access to HTML docs (even tries hard to support broken or janky
markup). This is not required, btw, and will "not work" gracefully if
you don't have lxml.html installed. Note that this specific feature
also requires lxml2, which may still be in beta.
