Kernel gets mixed in to an object, so you need to stub it on the object itself.
describe Newsreader do
it "should open the uri" do
@reader = Newsreader.new
@reader.should_receive(:open_uri).with "http://example.com/feed.xml";
@reader.grab_feed "http://example.com/feed.xml";
end
end
class Newsreader
def grab_feed(uri)
response = open_uri uri
end
end
