I am driving out a view and I want to test that a link is displayed.
The link_to code for the link is included in the layout for the view
rather than the view template itself.
Here''s my example:
it "should display a link to create a new zone" do
render "contexts/index.html.erb", :layout => "layouts/
contexts.html.erb"
response.should contain("sign out")
end
Firstly, my experiments suggest that the layout is only rendered if
the :layout attribute is included in the call to render. Is my
understanding correct?
Secondly, the link_to code only executes if the session contains a
piece of data (member id). How do I set up the session data in my view
spec?
Thanks.

See: http://rspec.info/rails/writing/views.html Whether the view (or layout) should be looking directly into the session and making decisions from what it sees, instead of trusting what it gets from the controller, is another question. "Is there a current user?" is _probably_ closer to your actual business rules than "Does the session contain a member id?" -- Have Fun, Steve Eley (sfeley at gmail.com) ESCAPE POD - The Science Fiction Podcast Magazine http://www.escapepod.org
Thanks Steve.
As suggested I started to wrtite a separate spec for the layout:
require File.expand_path(File.dirname(__FILE__) + ''/../../
spec_helper'')
describe "layouts/contexts.html.erb" do
it "should display a link to create a new zone" do
render "layouts/contexts.html.erb"
end
end
When I execute this, it complains of a missing method "sub_menu". This
method, along with others such as "main_menu", are called within the
layout. Unlike "main_menu" which is defined in my
"application_helper.rb" file, "sub_menu" is defined in the
helper file
for the controller "contexts". How do I get the spec to
"see" this
file and its contents when executed? I think It''s seeing
"main_menu".
Thanks.

A "describe" block is really just a prettified form of class definition, so you can include any modules you like in it. Although (warning: continued smartassery here) I''m also wondering why it''s a good idea to call a method defined in a specific controller''s helper from a global layout. Is this layout only used by that controller? If not, why isn''t the method in application helpers? -- Have Fun, Steve Eley (sfeley at gmail.com) ESCAPE POD - The Science Fiction Podcast Magazine http://www.escapepod.org
