### BEGIN INIT INFO |
I'm a fan of MiniTest::Spec. It strikes a nice balance between the simplicity of TestUnit and the readable syntax of RSpec. When I first switched from RSpec to MiniTest::Spec, one thing I was worried I would miss was the ability to add matchers. (A note in terminology: "matchers" in MiniTest::Spec refer to something completely different than "matchers" in RSpec. I won't get into it, but from now on, let's use the proper term: "expectations").
Let's take a look in the code (I'm specifically referring to the gem, not the standard library that's built into Ruby 1.9):
# minitest/spec.rb
module MiniTest::Expectations
require 'bigdecimal' | |
require 'csv' | |
require 'pp' | |
class Stats | |
include Enumerable | |
def initialize(array) | |
standardize_array(array) | |
end |
begin | |
require 'hirb' | |
rescue LoadError | |
# Missing goodies, bummer | |
end | |
if defined? Hirb | |
# Dirty hack to support in-session Hirb.disable/enable | |
Hirb::View.instance_eval do | |
def enable_output_method |
