test.chomp = gets

and

test = gets.chomp

Will give you different results.
test.chomp will return a chomped value but doesn't permanently chomp  
the value in test
you would need to do

test.chomp! = gets

This is the destructive version of chomp, methods ending with !  
usually modify the receiver in place, others usually don't.
The reason my version doesn't need chomp! is because it takes the  
chomped value of gets and assigns that to test.
