Hi,  
I’m trying to start using cucumber. I’ve done login, logout scenarious,  
but stumbled in CAPTCHA validation on user registration page. As I get I  
should stub CAPTCHA validation method. I guess I should implement  
stubbing Given step or include stubbing code in Before filter?

I use validates\_captcha gem, thus instance method to stub is

module ValidatesCaptcha  
module ModelValidation  
module InstanceMethods  
private  
def validate\_captcha  
# doing nothing means passing  
end  
end  
end  
end

I’ve read these posts  
[http://vinsol.com/blog/2006/07/21/rails-captcha-and-testing-using-mock-objects/](http://vinsol.com/blog/2006/07/21/rails-captcha-and-testing-using-mock-objects/)

but still don’t get where should I put stubbing code, should I call  
stub! method and if so, of which object?
