One of the problems with the rspec_on_rails_on_crack (git://activereload.net/rspec_on_rails_on_crack.git) was that the redirection examples had horrible descriptions.

describe FooController, "GET /index" do
  it_redirects_to { foo_path }
end

The route goes in a ruby proc because routes aren’t available from the context of the example group. They’re only available from inside a running example. But this is what the description looks like when running rake spec:doc:

FooController GET #index
  - redirects to #<Proc:0x0224e7d8@./spec/controllers/foo_controller_spec.rb:68>

Solution? Install the ParseTree and ruby2ruby gems and add this to #it_redirects_to:

route.to_ruby.gsub(/(^proc \{)|(\}$)/, '').strip

FooController GET #edit
- redirects to "foo_path(1)"
