jnunemaker / Tests Is Wrong

Created October 21, 2009 04:12 — forked from rtomayko/Tests Is Wrong

	In response to all the responses to:

	http://twitter.com/rtomayko/status/1155906157

	You should never do this in a source file included with your library,
	app, or tests:

	require 'rubygems'

	The system I use to manage my $LOAD_PATH is not your library/app/tests
