Excellent Thank you!! That worked like a charm...
So to answer the persons original question...
Use RSpec and this is an example of a complete helper rspec that tests
the HTML generated...
require File.dirname(__FILE__) + '/../spec_helper'
describe ApplicationHelper do
include ActionView::Helpers
include Haml::Helpers
it "should display flash" do
@haml_is_haml = true
@haml_stack = [Haml::Buffer.new(:attr_wrapper => "'")]
for name in [:notice, :warning, :error]
flash[name]= "flash #{name.to_s} message"
capture_haml{
display_flash
}.should =~ /<div class='#{name.to_s}'>\s+#{flash[name]}\s+<\/
div>/
flash[name]= nil
end
end
end
for something in application_helper.rb...
def display_flash
for name in [:notice, :warning, :error]
if flash[name]
open :div, flash[name], {:class => name.to_s}
end
end
nil
end
