Substruct engine + rspec_on_rails not co-operating

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 :slight_smile: (not that I've tried that anyway)

I’m at a loss here because I have no clue what rspec is…url?

RSpec is a behaviour driven development (BDD) framework - 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)

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 (Some AI Koans) I read almost ten years ago. I didn't think it ever actually happened!!!

Anyway as long as rspec is working I'm happy
