Shared examples don't support parameterization, but macros do. Try
something like this:
module Macros
def shows_yearly_archive_for(requests={})
requests.keys.each do |action|
it "should assign a list of yearly archives on
#{requests[action]} #{action}" do
Factory.create(:post, :published_at => Time.local(2009,02,01))
Factory.create(:post, :published_at => Time.local(2009,01,01))
Factory.create(:post, :published_at => Time.local(2008,01,01))
Factory.create(:post, :published_at => Time.local(2007,01,01))
Factory.create(:post, :published_at => Time.local(2001,01,01))
send requests[action], action
assigns[:years].should == [ 2009, 2008, 2007, 2001 ]
end
end
end
end
describe SomeController do
extend Macros
shows_yearly_archive_for :index => :get
end
You can also extend with Macros from the config in spec_helper:
Spec::Runner.configure {|c| c.extend(Macros, :type => :controller)}
