module Riot
  # Asserts the result of the test is a non-truthy value. Read the following assertions in the way Borat
  # learned about humor:
  #
  #   asserts("you are funny") { false }.not!
  #   should("be funny") { nil }.not!
  #
  # Thusly, Borat would say "You are funny ... not!" The above two assertions would pass because the values
  # are non-truthy.
  #
  # You can also apply not to the negative assertion (denies), but I'm not sure how much sense it would make.
  # It would be kind of like a double negative:
  #
  #   denies("you are funny") { true }.not!
