When an event occurs,
then ensure some outcomes.

 Given a BDD scenario 
   When an event occurs 
     It should evaluate to 1 
     It should also evaluate to 3 
     It should perform another evaluation 
     It should also perform another evaluation 
   When using Setup() in extended-style 
     It should increment count to 1
