Which would look something like this:

>>> view = zapi.getMultiAdapter((self.event1, self.request), 
>>> name="daterange_display")

To register the view in python for a non-functional doctest something
like this would work (maybe someone can correct me, because I've got
IBrowserRequest twice in there but it does work):

>>> component.provideAdapter(YourViewClass, [IYourInterface, IBrowserRequest],  
>>> \
... IBrowserRequest, name='daterange_display')

Yes. But all the same I do use a quick doctest to check that the view
class behaves as expected before going on to testbrowser functional
tests (which take longer to run). I save a bit of time then catching
silly import and syntax errors and tuning the view class.
