Hi,

I am trying to upgrade my existing application from Rails 2.0.2 to  
2.3.5. I am getting the following error while I run the test:

ruby test/unit/address\_test.rb --name test\_address2\_required\_in\_jp

Loaded suite test/unit/address\_test  
Started  
E  
Finished in 0.001887 seconds.

1. Error:  
test\_address2\_required\_in\_jp(AddressTest):  
NoMethodError: You have a nil object when you didn’t expect it!  
You might have expected an instance of ActiveRecord::Base.  
The error occurred while evaluating nil.[]  
test/unit/address\_test.rb:195:in `test_address2_required_in_jp' test/test_helper.rb:134:in`run’

In 195th line I just used a fixture like addresses(:jp\_address) which  
worked well before rails upgrading.

Thanks,  
Arun
