[rspec-users] skip pending (was Re: Posted this in "dev" last night but I'm not sure that anyone reads it)

[Jonathan Linowes]

The way I've started using story runner is to write the story and  
scenarios, and then implement each step incrementally. The order that  
I implement is not necessarily the order its logically written. Lets  
say I want to get the story working without the authentication, so a  
Given clause and a Then clause might be pending; but I'd still want  
the story to run though the rest of the stuff. I tried calling pending 
("TO DO") in the do end block,but that gave same result. Well, what  
if we added a new method, like skip_this_because("authentication not  
implemented yet") ?? :)
