[Zope] zope.testbrowser, how to?

[Basil Shubin]

Hi friends,

I want use zope.testbrowser for testing my sites, but before write it as 
DocTest I want execute each statemnt interactively in python shell. I 
don't know any way to see where it's works, what value it returns, what 
error I can get and how this error should looks is python... It's why I 
want check it in python shell.

What the problem?

First, if execute following code in python shell:

 >>> from zope.testbrowser import Browser
 >>> browser = Browser()
 >>> browser.open('http://localhost/Plone')

I have got:

Traceback (most recent call last):
   File "<stdin>", line 1, in ?
   File "/usr/lib/python2.4/site-packages/zope/testbrowser/browser.py", 
line 220, in open
     self.mech_browser.open(url, data)
   File "/usr/lib/python2.4/site-packages/mechanize/_mechanize.py", line

     return self._mech_open(url, data)
   File "/usr/lib/python2.4/site-packages/mechanize/_mechanize.py", line

     self._response = UserAgent.open(self, self.request, data)
   File "/usr/lib/python2.4/urllib2.py", line 358, in open
     response = self._open(req, data)
   File "/usr/lib/python2.4/urllib2.py", line 376, in _open
     '_open', req)
   File "/usr/lib/python2.4/urllib2.py", line 337, in _call_chain
     result = func(*args)
   File "/usr/lib/python2.4/site-packages/zope/testbrowser/testing.py", 
line 112, in http_open
     return self.do_open(PublisherConnection, req)

line 69, in request
     self.response = self.caller(request_string, handle_errors)
   File

     environment)
   File 
"/usr/lib/python2.4/site-packages/zope/app/testing/functional.py", line 
606, in chooseRequestClass
     return chooseClasses(method, environment)
   File 
"/usr/lib/python2.4/site-packages/zope/app/publication/httpfactory.py", 
line 33, in chooseClasses
     factory = factoryRegistry.lookup(method, content_type, environment)
   File 
"/usr/lib/python2.4/site-packages/zope/app/publication/requestpublicationregistry.py", 
line 97, in lookup
     raise ConfigurationError('No registered publisher found '
zope.configuration.exceptions.ConfigurationError: No registered 
publisher found for (GET/)

Second, if I add Zope src dir into PYTHONPATH, than I got following:
 >>> from zope.testbrowser import Browser
Running tests at level 1
Total: 0 tests, 0 failures, 0 errors

and than it drops me out from python shell.

So, question is: suppose I don't know what value/error I can/should 
recive after each statement, so how can I write DocTest? I need somehow 
to know to what I should expect, but how?

Thanks for any advices!

PS. Sorry for my bad english
