ruby gem contrast before deployment

i'm formulating gem has

• several scripts bin directory


• the concentration classes lib directory


• and several tests exam directory

supertool
 bin
   toola
   toolb
 lib
   supertool
     supertool.rb
     helper.rb
 test
   tc_main.rb
   tc_etc.rb

now, run tests before i even exercise gem, i have following dash during tip tests:

base = file.basename(dir.pwd)
if bottom == 'test' || bottom =~ /supertool/
   dir.chdir('..') bottom == 'test'
   $load_path.unshift(dir.pwd + '/lib')
   dir.chdir('test') bottom =~ /supertool/
end

this seems empty though, generally i have put scripts bin office too. there improved proceed sourroundings adult sourroundings exam gems before installed? i'm certain it's something rudimentary i only can't find. rudimentary couple right place assistance lot :)
