Ruby Forum RSpec > undefined method `assert_select'

I'm having trouble getting the specs to run for a plugin where I want to
fix a bug. (I've actually already found and fixed the bug, but I don't
want to submit a fix without a test!) When I started the specs weren't
running, but it may be that I'm using Rails 2.3.3 and the plugin has
been tested on 2.1 and earlier. I went through writing a spec for a very
simple plugin to get some perspective on how things fit together, and
I've resolved some issues, but still see this error:

$ spec
vendor/plugins/openlaszlo_plugin/spec/swfobject_view_helper_spec.rb
FFFFFFF

1)
NoMethodError in 'ActionView::Helpers::SwfObjectHelper swfobject_tag
should call swfobject.embedSWF'
undefined method `assert_select' for
#<ActiveSupport::TestCase::Subclass_1::Subclass_1:0x2281278>
./vendor/plugins/openlaszlo_plugin/spec/swfobject_view_helper_spec.rb:17:

line 17 is:
      html.should have_tag('script', /swfobject.embedSWF/)

Can anyone give me a hint?

Thanks,
Sarah

I order to use have_tag, it appears I have to include:

# just enough infrastructure to get 'assert_select' to work
require 'action_controller'
require 'action_controller/assertions/selector_assertions'
include ActionController::Assertions::SelectorAssertions

borrowed from: http://intertwingly.net/stories/2009/05/06/checkdepot.rb

Odd, because it seems like this used to work without that in a previous 
version of Rails, but I would need to investigate more to isolate what 
went wrong.  I figured I would go ahead and post this as something that 
works.

Confirmed that this is is required in Rails 2.3.2 and not in 2.1.0, 
although I still don't understand why.

Me neither :)

What version of rspec are you using?

I just worked on this a bit with RailsBridge mentor, Zach Moazeni, who 
figured out that the problem was that I had not specifies a type for my 
view helper example group:

describe SwfObjectHelper, :type => :helper do

I thought I would post it here in case anyone else runs into the same 
issue.

FYI - if you put this file in spec/helpers/swf_object_helper_spec.rb,
then :type => :helper is implied, so you don't have to make it
explicit.

Nice.

By the way, I've been enjoying The RSpec Book, but it looks like I had 
to figure out view helpers before that chapter was ready.  Thank for 
your help on this list!

just curious... are there any other magic directories I should know 
about?

All directories under spec/ are potentially magic - rspec will always
look at spec/:directory/:filename and see if it has an example group
type registered for whatever directory is. So if there *is* a foo
example group type, it will be used for any spec file in spec/foos.

rspec-rails uses that feature of rspec to implicitly load custom
groups for models, views, controllers and helpers in spec/models,
spec/views, spec/controllers and spec/helpers.

David
