[Rails] Re: ruby koans don't understand the principle sandwhich code

[7stud --]

 But I don't get the principle.

There is no such principle as the Sandwich principle.  The principle is 
Don't Repeat Yourself(DRY).  So if you find yourself writing the same or 
similar code over and over again, try to figure out a way to extract the 
repeated part into a method.  That way you can write the code once in 
the method, and then call the method when needed.

Don't like it, unit test looks ugly compared to RSpec, hard to read.
