Hi guys,

Need some help.

I am using Rails 2.0 and while writing functional test, I encountered  
the following problem

class UserControllerTest \< ActionController::TestCase  
fixtures :users  
…  
def do\_something  
attempt\_login(users(:valid\_user)) # assuming valid\_user is a  
proper line in  
…  
end

def attempt\_login(user)  
post :login, :user =\> { :login =\> user.login, :password =\>  
user.password }  
end

Running the test:  
…

1. Error:  
do\_something(UserControllerTest):  
NoMethodError: You have a nil object when you didn’t expect it!  
The error occurred while evaluating nil.login  
test/functional/user\_controller\_test.rb:41:in `attempt_login' test/functional/user_controller_test.rb:32:in`do\_something’  
/usr/lib/ruby/gems/1.8/gems/activesupport-2.0.2/lib/active\_support/  
testing/default.rb:7:in `run’

- I tried putting fixtures :users within setup, still the same  
problem. This works if I derive Test::Unit::TestCase instead of the  
new rails 2.0 default class
