[rspec-users] Getting Class in Shared Behaviours

[Nathan Sutton]

Some of this clears up my issues around sharing behaviors that you can  
pass parameters to.  I was doing a hackish solution before by  
including a module then calling a method it provides, but now I can  
have shared behaviors and just have them call specific methods which  
then become a convention to define.  It still feels hackish, but not  
nearly as much.  Is there another way?
