Question

Is there a quick (command OR gem OR test framework) to ensure that all View variables point to Controller variables?

I worked on a Rails app where a View variable was spelled incorrectly, and therefore did not display the data being called in the Controller. For example, @person.name is not displayed in the view.

Controller  
|- @person.name = 'first'  
|- @person.email = '[e-mail]'  
|- @person.cell = '123-456-7890'  

View  
|- display @person.nameE    # => NoMethodError
|- display @person.email    # => [e-mail]
|- dispaly @person.cell     # => 123-456-7890

This will result in @person.name not displaying on the view since it is incorrectly pointed to.

Actually, @person.nameE won’t return nil — it’ll raise NoMethodError. As long as you have a test loading that view, you’ll see it blow up when you run it.
