Hi,

Please Help, I am trying to run tests on my website but it fails each  
and every time I think its not even running test.  
ruby version: ruby 1.8.6 (2008-03-03 patchlevel 114) [x86\_64-linux]  
rails version: Rails 2.3.5

when I did this from console  
ruby test/units/activity\_test.rb

it throws this error (and no other test is running)  
/usr/lib64/ruby/gems/1.8/gems/mysqlplus-0.1.1/lib/mysqlplus.rb:18:  
warning: parenthesize argument(s) for future version  
/usr/lib/ruby/site\_ruby/1.8/rubygems/source\_index.rb:324:in `search': stack level too deep (SystemStackError) from /usr/lib/ruby/site_ruby/1.8/rubygems/source_index.rb: 323:in`select’

from ./test/unit/…/test\_helper.rb:2  
from test/unit/activity\_test.rb:1:in `require’  
from test/unit/activity\_test.rb:1

My test case is very simple

this is my activity\_test.rb

require File.dirname( **FILE** ) + ‘/…/test\_helper’

class ActivityTest \< ActiveSupport::TestCase

def setup  
end

def test\_per\_page  
assert\_instance\_of Fixnum, Activity.per\_page  
end  
end

I do not having any idea why its not running. Please help

Thanks  
Sumeet
