Error in running functional testing

Hi,

I got the following error when i tried to run functional testing:
D:\Uni\Programming\Ruby\Project\test>ruby
functional\devices_controller_test.rb
c:/ruby/lib/ruby/gems/1.8/gems/activesupport-1.2.5/lib/active_support/dependenci
es.rb:200:in const_missing': uninitialized constant ApplicationController (Name Error) from D:/Uni/Programming/Ruby/Project/config/../app/controllers/devices_c ontroller.rb:1 from c:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:18:inre

c:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:18:in re quire' from c:/ruby/lib/ruby/gems/1.8/gems/activesupport-1.2.5/lib/active_suppo rt/dependencies.rb:214:inrequire’
from functional/devices_controller_test.rb:2

I didn’t have this problem before.

Any idea?

Thanks,

Lantis.
