I don't recommend using Test::Unit assertions in IRB.

This will load a Ruby source (.rb or dynamic library) regardless of
whether it's been included before. It does not have automatic
resolution (e.g., require 'foo/bar' would need to be load
'lib/foo/bar.rb'), if lib/foo/bar.rb is the appropriate relative path
from the current working directory.

This will load a Ruby source once and only once. This is most common.

This is the mechanism used for mixing in modules. This is wholly
unrelated to require and load.
