Hi everybody

I have some basic problems with my functional tests. In my controller, I  
have the method “index” and “list”.

def index  
list  
render :action =\> ‘list’  
end

def list  
@person\_pages, @persons = paginate :persons, :per\_page =\> 200  
end

Now I would like to test the controller. So I wrote the test-method like  
the following:

def setup  
@controller = CurrencyController.new  
@request = ActionController::TestRequest.new  
@response = ActionController::TestResponse.new  
end

def test\_index  
get :index  
assert\_response :success  
assert\_template ‘list’  
end

But it doesn’t work! Why? I receive only these error message:

> NoMethodError: You have a nil object when you didn’t expect it!  
> You might have expected an instance of Array.  
> The error occured while evaluating nil.-

We’ll need more information, as what you’ve posted looks fine. What line  
is  
the NoMethodError thrown from?

Yes, I pulling fixtures into my tests. About my data schema. I clone  
with rake the whole structure to the test environment.

Are you properly pulling in fixtures into your tests (fixtures  
:persons)?

Is your data schema in working order (migrations, fixture YAML files,  
etc)?
