testing helpers with 'haml_tag'

Question

module FooHelper
  def foo
    haml_tag(:div) do
      haml_content("bar")
    end
  end
end

When I test this I get:

NoMethodError: undefined method `haml_tag'

This code is perfectly valid and works in a development/production environment.

It's something to do with having the haml helpers properly loaded in the test environment.

Thanks!

It looks like the Rails test scaffold isn't including Haml::Helpers in its context. If you're using Test::Unit, you can probably just include it yourself in the test class. You'll also want to run Haml::Helpers#init_haml_helpers in the test setup so that all the Haml stuff is properly initialized.
