Testing flash.keep in Rails 3.2
Mike Naberenzy once posted about testing
flash.keep in Rails. His method doesn’t seem to work
since Rails 2.1.
Here’s how I got a passing spec.
it 'keeps the search_params flash' do # Make two get requests to simulate the flash getting swept after the # first response. get :something, nil, nil, :foo => 'bar' get :something expect(flash[:foo]).to eq('bar') end
With an empty controller, the spec fails.
class SomethingController < ApplicationController def something end end
Keeping the flash allows the spec to pass:
class SomethingController < ApplicationController def something flash.keep(:foo) end end
