RubyMine, why I can't debug spec files?

Question

I am trying to debug a spec test using RubyMine, but, I get:

uninitialized constant QuizzesController

here is the full error:

Fast Debugger (ruby-debug-ide 0.4.17.beta8, ruby-debug-base 0.11.30.pre4) listens on 127.0.0.1:41134 /home/sam/Documents/RoR/course_builder/spec/controllers/quiz_spec.rb:1:in <top (required)>': uninitialized constant QuizzesController (NameError) from /home/sam/.rvm/gems/ruby-1.9.3-p0@global/gems/rspec-core-2.7.1/lib/rspec/core/configuration.rb:459:in load' from /home/sam/.rvm/gems/ruby-1.9.3-p0@global/gems/rspec-core-2.7.1/lib/rspec/core/configuration.rb:459:in block in load_spec_files' from /home/sam/.rvm/gems/ruby-1.9.3-p0@global/gems/rspec-core-2.7.1/lib/rspec/core/configuration.rb:459:in map' from /home/sam/.rvm/gems/ruby-1.9.3-p0@global/gems/rspec-core-2.7.1/lib/rspec/core/configuration.rb:459:in load_spec_files' from /home/sam/.rvm/gems/ruby-1.9.3-p0@global/gems/rspec-core-2.7.1/lib/rspec/core/command_line.rb:18:in run' from /home/sam/.rvm/gems/ruby-1.9.3-p0@global/gems/rspec-core-2.7.1/lib/rspec/core/runner.rb:80:in run_in_process' from /home/sam/.rvm/gems/ruby-1.9.3-p0@global/gems/rspec-core-2.7.1/lib/rspec/core/runner.rb:69:in run' from /home/sam/.rvm/gems/ruby-1.9.3-p0@global/gems/rspec-core-2.7.1/lib/rspec/core/runner.rb:10:in block in autorun' from /home/sam/.rvm/gems/ruby-1.9.3-p0@global/gems/ruby-debug-ide-0.4.17.beta8/lib/ruby-debug-ide.rb:127:in debug_load' from /home/sam/.rvm/gems/ruby-1.9.3-p0@global/gems/ruby-debug-ide-0.4.17.beta8/lib/ruby-debug-ide.rb:127:in debug_program' from /home/sam/.rvm/gems/ruby-1.9.3-p0@global/gems/ruby-debug-ide-0.4.17.beta8/bin/rdebug-ide:95:in' from -e:1:in load' from -e:1:in'

/quiz_spec.rb line 1 is describe QuizzesController do

I get this error only when trying to debug the spec file, the spec file will work normally if I just run it without debugging.

I am using spork, all spec tests run fine without debugging, but, I am stuck in trying to debug any of them, any help please ?

Answer 1

You should put require 'spec_helper' in the first line of the spec file.
