Unit testing /lib directory...

Hi

I'm writing small replacement for ActiveRecord to support columns oriented databases (HBase). I put all of my code into /lib folder and created small rake file into /lib/tasks to support unit testing:

#----- start of file ----- namespace :test do   Rake::TestTask.new(:lib) do |t|     t.libs << "lib"     t.libs << "test"     t.pattern = 'test/lib/**/*_test.rb'     t.verbose = true   end   Rake::Task['test:lib'].comment = "Run the tests in test/lib" end #---- end of file -------

Now i'm able to write unit tests in /test/lib.

My main problem is that my unit tests now do not see any rails loaded classes, e.g. one of my unit tests uses ActiveRecord::Errors but i'm getting :

"NameError: uninitialized constant ActiveRecord::Errors"

Do I need to include (require) all rails classes in my unit tests just to be sure that everything works fine? (in general I included rubygems and active_record but still getting same error)? Any ideas, comments, ...?
