FWIW, this his the spot with me...

True.  I guess Alex' statement about "works via ZCML only"  made me
offer the above suggestion as a
hail-mary-aha-this-is-obvious-and-maybe-I-dont-need-to-think-very-hard-about-helping-here
 answer. ;-)  But alas, ZCML vs. scanning isn't the difference at all, so I'm 
not sure what worked via ZCML and what didn't work via scanning at all.

As far as integration testing of a view, you might be able to use the
render_view API if you can arrange for the context, request, and view
name to be right:

That won't help, since the ViewIntegrationTests linked to my Alex still 
call the view directly, which won't trigger any of the stuff that 
venusian does, or any imperative configuration, or even anything 
configured via zcml unless `my_view` happens to render its own template 
inside the body of the function, which I'd guess most views avoid doing 
as it makes them harder to unit test...

cheers,

When you say scanning doesn't work, it's likely you're doing:

config.scan()

... in the test setup.  If so, you actually need to do:

config.scan('mypackage')

.. where mypackage is the name of the Python package holding the
application you're trying to test.

I'm not sure if it's the "right" way, but I use WebTest, a generic WSGI
testing framework:  http://pythonpaste.org/webtest/

The method described at
http://docs.repoze.org/bfg/current/narr/unittesting.html#creating-integration-testsdidn't
work for me (ie: I'm still getting a dict, instead of a response
object). I believe it doesn't work with decorators scanning, only with what
is configured in the zcml file.

Good luck,
Alex

[Repoze-dev] functional testing with @bfg_view

[Chris Withers]

Hi All,

I have a view that starts like this:

@bfg_view(renderer='templates/control.pt')
class Control:

 def __init__(self,request):
 self.request = request

 def __call__(self):
 ...
 return dict(
 ...
 )


I'd like to do a functional test, in particular checking that the 
template has no syntax errors in it and contains the data it should do 
by checking for strings in the returned response.

I got this far:

class TestView(TestCase):

 def setUp(self):
 self.request = testing.DummyRequest()
 self.config = Configurator()
 self.config.begin(request=self.request)
 self.config.scan(myapp)

 def tearDown(self):
 self.config.end()


 def test_render(self):
 view = Control(self.request)

But now what's the "right" way to actually get the to render the html, 
preferably also testing the path dispatch to '/' at the same time?

cheers,

Chris
