You are trying to visit the page for a 'forum' object (with ID=1) that  
does not exist in your database.

In each scenario, you need to imagine your application starts from a  
completely empty state, just like it would if you started the  
application with script/server.

You need a step in your scenario that says 'Given there is a Forum'  
which creates the record in the database.

If you don't mind me saying so, this question suggests to me that you  
have quite a bit to learn about Cucumber. While people on this list  
are pretty patient and helpful, they are also busy and will be more  
keen to help if you spend some time helping yourself too. I suggest  
you start with the recent railscast on Cucumber.
