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 figured I would go ahead and post this as something that works. Sarah ---

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! Sarah ---

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.
