Hi I promised a friend of mine I’d help update his online store. To get something up fast, I thought I’d try Substruct. But I can’t make rspec specs run with it installed. I’ve got the 1.2 RC 1 gem installed, and my environment.rb starts “module Engines; EdgeRails = true; end” I’ve succuessfully installed Engines and Substruct, got the database set up, and managed to rub Webrick and log in to the admin section. So the app seems fine. I generated a controller with “script/generate rspec\_controller stock\_list\_import”, but I can’t run it. rspec dies with the error below. This is the exact same error I had before I configured everything correctly (if I remember right, before I set the EdgeRails constant in Engines). I don’t understand why SubstructApplicationController is not available to the spec, because: - the spec requires spec/spec\_helper - spec/spec\_helper requires config/environment - config/environment requires config/boot AND calls Engines.start :substruct surely this is near enough the same as booting Webrick? Any ideas why it doesn’t work? And before anyone asks, I’m an rspec whore. Using Test::Unit IS out of the question 🙂 (not that I’ve tried that anyway) Ashley $ rake spec:controllers (in /Users/ashleymoran/Documents/Development/Stalmine/stalmine\_tech) /opt/local/bin/ruby -I"/opt/local/lib/ruby/gems/1.8/gems/rspec-0.7.4/ lib" “/opt/local/lib/ruby/gems/1.8/gems/rspec-0.7.4/bin/spec” “spec/ controllers/stock\_list\_import\_controller\_spec.rb” /opt/local/lib/ruby/gems/1.8/gems/activesupport-1.3.1.5618/lib/ active\_support/dependencies.rb:471:in `const_missing': uninitialized constant ApplicationController::SubstructApplicationController (NameError) from /Users/ashleymoran/Documents/Development/Stalmine/ stalmine_tech/config/../app/controllers/application.rb:5 from /opt/local/lib/ruby/vendor_ruby/1.8/rubygems/ custom_require.rb:27:in`gem\_original\_require’ from /opt/local/lib/ruby/vendor\_ruby/1.8/rubygems/ custom\_require.rb:27:in `require' from /opt/local/lib/ruby/gems/1.8/gems/ activesupport-1.3.1.5618/lib/active_support/dependencies.rb:489:in`require’ from /opt/local/lib/ruby/gems/1.8/gems/ activesupport-1.3.1.5618/lib/active\_support/dependencies.rb:337:in `new_constants_in' from /opt/local/lib/ruby/gems/1.8/gems/ activesupport-1.3.1.5618/lib/active_support/dependencies.rb:489:in`require’ from /Users/ashleymoran/Documents/Development/Stalmine/ stalmine\_tech/config/…/vendor/plugins/rspec/lib/rspec\_on\_rails.rb:1 from /opt/local/lib/ruby/vendor\_ruby/1.8/rubygems/ custom\_require.rb:27:in `gem_original_require' ... 20 levels... from /opt/local/lib/ruby/gems/1.8/gems/rspec-0.7.4/lib/spec/ runner/command_line.rb:21:in`run’ from /opt/local/lib/ruby/gems/1.8/gems/rspec-0.7.4/lib/spec/ runner/command\_line.rb:15:in `each' from /opt/local/lib/ruby/gems/1.8/gems/rspec-0.7.4/lib/spec/ runner/command_line.rb:15:in`run’ from /opt/local/lib/ruby/gems/1.8/gems/rspec-0.7.4/bin/spec:4 rake aborted!

RSpec is a behaviour driven development (BDD) framework - http:// [rspec.rubyforge.org/](http://rspec.rubyforge.org/) It’s like Test::Unit/TDD, but you get more benefit out of it faster, because it forces you to think about the problem in a more productive way. (IMHO, I’m an rspec fanboy) Ashley ---

Hmm I had a look last night, figured out that the Engines plugin modifies the $LOAD\_PATH variable, decided that must be broken when running rspec, so I ran it again to get the exact error message … and it worked :-S I don’t think I even changed anything… This reminds me of the story Tom Knight and the Lisp Machine (http:// [Some AI Koans](http://www.catb.org/jargon/html/koans.html)) I read almost ten years ago. I didn’t think it ever actually happened!!! Anyway as long as rspec is working I’m happy Ashley
