## this my first rspec test, it is very simple

> 

require File.expand\_path(File.dirname( **FILE** ) + ‘/…/spec\_helper’)

describe Doc do  
fixtures :docs  
before(:each) do  
@doc=docs(:yjn\_bjy)  
end

## it “should create a new instance given valid attributes” do true end end \<----------------------------------------------------------------------------------------------------------------------------------------- after run “spec -fs spec\models\doc\_spec.rb” at cmd line,it report this error

> 

1. 

NoMethodError in ‘Doc should create a new instance given valid  
attributes’  
undefined method `key?’ for #String:0x46b1df0  
\<-----------------------------------------------------------------------------------------------------------------------------------------

My environment:  
OS:Windows  
Rails:2.2.2  
RSpec:1.1.11  
rspec-rails:1.1.11  
IDE:Netbeans6.5  
Ruby:1.8.6

I use rspec\_scaffold to generate these codes,and really confused about  
this problems.  
Hope for your suggestion!

## There’s probably a stack trace associated with that error, try looking in that.
