RSpec - testing multiple expectations across routes - ruby

Question

I'm attempting to use shared_examples as a way to repeat expectations across multiple routes. In particular, I want to test whether some static assets in my header and footer are loading. However, I get an error saying that:
RSpec::Core::ExampleGroup::WrongScopeError: `it_behaves_like` is not available from within an example (e.g. an `it` block) or from constructs that run in the scope of an example (e.g. `before`, `let`, etc). It is only available on an example group (e.g. a `describe` or `context` block).
Now, I'm not sure how to remedy this. This is my current setup.
shared_examples_for 'a page' do
describe 'should load static assets' do
it 'header, footer and icons' do
expect(page).to have_css 'footer.footer'
expect(page).to have_css '#navbar-brand'
brand = page.first(:css, '#navbar-brand')
visit brand[:src]
expect(page.status_code).to be 200
end
end
end
describe 'site pages should load static assets on requests', { :type => :feature } do
after :all do
it_behaves_like 'a page'
end
it 'home page' do
visit '/'
expect(page).to have_css 'div#main-menu a', count: 5
page.all('link[rel~="icon"]').each do |fav|
visit fav[:href]
page.status_code.should be 200
end
expect(page).to have_css 'div#main-menu'
...
end
it 'about page should have icons, footer and a header' do
visit '/about'
...
end
end
Another attempt was this:
describe 'home page' do
it_behaves_like 'a page'
end
Both fail for the same reason above. So, if I want to check the same things on every page, what is a better solution?

Answer 1

In RSpec 3 this should work
require 'spec_helper'
shared_examples 'a page' do
it 'has a header' do
expect(page).to have_css 'footer.footer'
end
it 'has a brand' do
expect(page).to have_css '#navbar-brand'
end
it 'points out to brand page' do
brand = page.first(:css, '#navbar-brand')
visit brand[:src]
expect(page.status_code).to be 200
end
end
describe 'home page' do
before { visit '/' }
it_behaves_like 'a page'
it 'does something else' do
# ...
end
end
Alternatively you could use a block
describe 'home page' do
it_behaves_like 'a page' do
before { visit '/' }
end
end
