I packed it up into a useful reusable gem ;)
http://github.com/kristianmandrup/rspec-action_view
Only these dependencies :)
require 'rspec'
require 'action_view'
require 'active_support/railtie'
require 'action_view/template/handlers/erb'
Now allows for this DSL
describe "My ViewHelpers" do
it "should render content as expected" do
setup_action_view do
tests MyViewHelper, MyOtherViewHelper
end
with_action_view do |view|
view.tab_for('kristian') { 'hello' }.should match /kristian/
view.hello('david') { 'hello' }.should match /david/
with_action_view do |view|
view.with_template(%{
<%= tab_for('kristian') { 'hello' } %>
}).should match /hello/
end
end
end
Enjoy!
