Hey guys. I''ve told one of my controllers to not render a layout for a
certain action:
layout false, :only => :map_info_window
Now I''m trying to spec that, but this:
it ''should not render a layout'' do
controller.expect_render :layout
do_get
end
fails with this:
Spec::Mocks::MockExpectationError in ''PropertiesController handling
GET /properties/1/map_info_window should not render a layout''
Mock ''expect_render_mock_proxy'' expected :render with
(:layout) once,
but received it 0 times
I''m using RSpec v1.1.4 . I know it''s old, but I
haven''t gotten around
to upgrading yet!

Unfortunately, that didn''t work either. It seems that the controller object in the "controller" variable doesn''t actually receive the call to #layout : Spec::Mocks::MockExpectationError in ''PropertiesController handling GET /properties/1/map_info_window should not render a layout'' Mock ''PropertiesController'' expected :layout with (false, {:only=>:map_info_window}) once, but received it 0 times Thanks, Nick

One trick for spec''ing class level declarations is to set the expectation and reload the class file. I''ve seen this used successfully with models: ActiveRecord::Base.should_receive(:has_many).with(:cows) load RAILS_ROOT + "/app/models/cowboy.rb" Sadly, I''ve not seen that succeed with controllers. I''m not clear why yet, but there is something in Rails'' internals that make it a challenge. One way I''ve handled this successfully is to integrate_views for this one example (in its own group) and specify that html elements from the layout are not present in the form. It''s a brittle example, but it''s only one. Any better approaches out there?
