The above assertion likely won't work, as you're using a
Zend_Http_Response, and not the controller response object. You'll want
to check your response codes and/or the page content instead.

The above should still work.

That works, but it is dependent on having the web server up and running.
I typically like my tests to be able to run with or without using the
web server -- I think of the tests as my sanity check prior to pushing
live.

Sure, there's a little more work to get the test case ready, but most of
that work is in the setUp() method -- which is only done once. The
actual test cases are basically as straightforward as the test you show
above -- create your request, dispatch it, and then run your assertions
against the response.
