Railers:

Here’s a non-heinous view test, via the mental serenity that is ZenTest:

class FrogSpeciesViewTest \< Test::Rails::ViewTestCase  
def test\_species\_list  
frog = frogs(:Ollotis\_periglenes)  
locals = {  
:frog\_genera =\> Species.find\_all\_by\_genera(‘Bufo’)  
}  
render :partial =\> ‘partials/species\_list’, :locals =\> locals  
end  
end

So far so good. But what if we want to pass params in? We can’t seem  
to find a hook for them, and if we pass them as a local something  
blots them out. Any help?
