rspec users - Sep 2008 - Helpers that call helpers not working in specs?

I''m trying to test some of my helpers.  I have one helper (in module
LocationsHelper) that calls a helper/method in ApplicationHelper.  If I
include ApplicationHelper and LocationHelper in my spec, and then I call the
helper using the "helper." scope:
  helper.location_tree(''Portland'')

then it complains that it can''t find the other helper it uses from
ApplicationHelper.  If instead, I call it directly:

  location_tree(''Portland'')

Then, it can''t find the Rails'' generated URL helpers (e.g.
"location_path"
or "location_url").  How do I make it so that all the dependencies or
Rails''
included stuff is found?

You don''t need to include the helpers if you are using the helper
object. You should be able to do just this:

describe LocationsHelper do
  it "should ..." do
    helper.location_tree(''Portland'').should ...
  end
end

Have you tried that? Does it fail?

If I don''t include them, then the helpers in LocationsHelper
can''t find/use
the helpers in ApplicationHelper.  Maybe this will help illustrate:
test code:

describe LocationsHelper do
  describe "location tree" do
    it "should not show siblings for state, country, or root level
locations" do
      helper.location_tree(@oregon).should_not include_text(@hawaii.name)
    end
  end
end

The location_tree method is defined in the module/helper LocationsHelper.
 But, it calls ApplicationHelper.markaby.  When I run the above test, it
can''t find the markaby method/helper.  It will only find markaby if I
remove
the leading "helper." from in front of the call, and also include
ApplicationHelper (including this, when using helper. doesn''t remedy
it).

OK - in the short run, I''d do this as a workaround instead:

  helper.extend ApplicationHelper

You can do that in a before block or in the examples directly.

This is a better option because you''ll soon not have direct access to
the helper methods in the examples except through the helper object.

Next question is whether rspec-rails should just include the
ApplicationHelper module into the helper object. My instinct is yes.
WDYT?

Cheers,
David

Thanks, that did the trick.

And for including ApplicationHelper, I would say it should include it -
because that would parallel Rails'' standard behavior.
