Actually, it turns out that you can do this in a view spec:
render "/path/to/my/file.html.erb", :layout => "application"
and it will render with the layout. So you *could* (in theory, I
haven't done this yet) do something like this:
# spec/resources/views/layout_example.html.erb
<div>yielded from layout</div>
# spec/views/layouts/application.html.erb_spec.rb
require File.dirname(__FILE__) + '/../../spec_helper'
describe "/layouts/application" do
it "should yield" do
render "/../../spec/resources/views/layout_example.html.erb",
:layout => "application"
response.should have_tag('div','yielded from layout')
end
it "should have title" do
render "/../../spec/resources/views/layout_example.html.erb",
:layout => "application"
response.should have_tag("div.idbar","My Killer App")
end
...
end
