+
+== DESCRIPTION:
+
+minitest provides a complete suite of testing facilities supporting
+TDD, BDD, mocking, and benchmarking.
+
+ "I had a class with Jim Weirich on testing last week and we were
+ allowed to choose our testing frameworks. Kirk Haines and I were
+ paired up and we cracked open the code for a few test
+ frameworks...
+
+ I MUST say that minitest is *very* readable / understandable
+ compared to the 'other two' options we looked at. Nicely done and
+ thank you for helping us keep our mental sanity."
+
+ -- Wayne E. Seguin
+
+minitest/unit is a small and incredibly fast unit testing framework.
+It provides a rich set of assertions to make your tests clean and
+readable.
+
+minitest/spec is a functionally complete spec engine. It hooks onto
+minitest/unit and seamlessly bridges test assertions over to spec
+expectations.
+
+minitest/benchmark is an awesome way to assert the performance of your
+algorithms in a repeatable manner. Now you can assert that your newb
+co-worker doesn't replace your linear algorithm with an exponential
+one!
+
+minitest/mock by Steven Baker, is a beautifully tiny mock (and stub)
+object framework.
+
+minitest/pride shows pride in testing and adds coloring to your test
+output. I guess it is an example of how to write IO pipes too. :P
+
+minitest/unit is meant to have a clean implementation for language
+implementors that need a minimal set of methods to bootstrap a working
+test suite. For example, there is no magic involved for test-case
+discovery.
+
+ "Again, I can't praise enough the idea of a testing/specing
+ framework that I can actually read in full in one sitting!"
+
+ -- Piotr Szotkowski
+
+Comparing to rspec:
+
+ rspec is a testing DSL. minitest is ruby.
+
+ -- Adam Hawkins, "Bow Before MiniTest"
+
+minitest doesn't reinvent anything that ruby already provides, like:
+classes, modules, inheritance, methods. This means you only have to
+learn ruby to use minitest and all of your regular OO practices like
+extract-method refactorings still apply.
+
+== FEATURES/PROBLEMS:
+
+* minitest/autorun - the easy and explicit way to run all your tests.
+* minitest/unit - a very fast, simple, and clean test system.
+* minitest/spec - a very fast, simple, and clean spec system.
+* minitest/mock - a simple and clean mock/stub system.
+* minitest/benchmark - an awesome way to assert your algorithm's performance.
+* minitest/pride - show your pride in testing!
+* Incredibly small and fast runner, but no bells and whistles.
+
+== RATIONALE:
+
+See design_rationale.rb to see how specs and tests work in minitest.
+
+== SYNOPSIS:
+
+Given that you'd like to test the following class:
+
+ class Meme
+ def i_can_has_cheezburger?
+ "OHAI!"
+ end
+
+ def will_it_blend?
+ "YES!"
+ end
+ end
+
+=== Unit tests
+
+ require 'minitest/autorun'
+
+ class TestMeme < MiniTest::Unit::TestCase
+ def setup
+ @meme = Meme.new
+ end
+
+ def test_that_kitty_can_eat
+ assert_equal "OHAI!", @meme.i_can_has_cheezburger?
+ end
+
+ def test_that_it_will_not_blend
+ refute_match /^no/i, @meme.will_it_blend?
+ end
+
+ def test_that_will_be_skipped
+ skip "test this later"
+ end
+ end
+
+=== Specs
+
+ require 'minitest/autorun'
+
+ describe Meme do
+ before do
+ @meme = Meme.new
+ end
+
+ describe "when asked about cheeseburgers" do
+ it "must respond positively" do
+ @meme.i_can_has_cheezburger?.must_equal "OHAI!"
+ end
+ end
+
+ describe "when asked about blending possibilities" do
+ it "won't say no" do
+ @meme.will_it_blend?.wont_match /^no/i
+ end
+ end
+ end
+
+For matchers support check out:
+
+https://github.com/zenspider/minitest-matchers
+
+=== Benchmarks
+
+Add benchmarks to your regular unit tests. If the unit tests fail, the
+benchmarks won't run.
+
+ # optionally run benchmarks, good for CI-only work!
+ require 'minitest/benchmark' if ENV["BENCH"]
+
+ class TestMeme < MiniTest::Unit::TestCase
+ # Override self.bench_range or default range is [1, 10, 100, 1_000, 10_000]
+ def bench_my_algorithm
+ assert_performance_linear 0.9999 do |n| # n is a range value
+ @obj.my_algorithm(n)
+ end
+ end
+ end
+
+Or add them to your specs. If you make benchmarks optional, you'll
+need to wrap your benchmarks in a conditional since the methods won't
+be defined.
+
+ describe Meme do
+ if ENV["BENCH"] then
+ bench_performance_linear "my_algorithm", 0.9999 do |n|
+ 100.times do
+ @obj.my_algorithm(n)
+ end
+ end
+ end
+ end
+
+outputs something like:
+
+ # Running benchmarks:
+
+ TestBlah 100 1000 10000
+ bench_my_algorithm 0.006167 0.079279 0.786993
+ bench_other_algorithm 0.061679 0.792797 7.869932
+
+Output is tab-delimited to make it easy to paste into a spreadsheet.
+
+=== Mocks
+
+ class MemeAsker
+ def initialize(meme)
+ @meme = meme
+ end
+
+ def ask(question)
+ method = question.tr(" ","_") + "?"
+ @meme.__send__(method)
+ end
+ end
+
+ require 'minitest/autorun'
+
+ describe MemeAsker do
+ before do
+ @meme = MiniTest::Mock.new
+ @meme_asker = MemeAsker.new @meme
+ end
+
+ describe "#ask" do
+ describe "when passed an unpunctuated question" do
+ it "should invoke the appropriate predicate method on the meme" do
+ @meme.expect :will_it_blend?, :return_value
+ @meme_asker.ask "will it blend"
+ @meme.verify
+ end
+ end
+ end
+ end
+
+=== Stubs
+
+ def test_stale_eh
+ obj_under_test = Something.new
+
+ refute obj_under_test.stale?
+
+ Time.stub :now, Time.at(0) do # stub goes away once the block is done
+ assert obj_under_test.stale?
+ end
+ end
+
+A note on stubbing: In order to stub a method, the method must
+actually exist prior to stubbing. Use a singleton method to create a
+new non-existing method:
+
+ def obj_under_test.fake_method
+ ...
+ end
+
+=== Customizable Test Runner Types:
+
+MiniTest::Unit.runner=(runner) provides an easy way of creating custom
+test runners for specialized needs. Justin Weiss provides the
+following real-world example to create an alternative to regular
+fixture loading:
+
+ class MiniTestWithHooks::Unit < MiniTest::Unit
+ def before_suites
+ end
+
+ def after_suites
+ end
+
+ def _run_suites(suites, type)
+ begin
+ before_suites
+ super(suites, type)
+ ensure
+ after_suites
+ end
+ end
+
+ def _run_suite(suite, type)
+ begin
+ suite.before_suite
+ super(suite, type)
+ ensure
+ suite.after_suite
+ end
+ end
+ end
+
+ module MiniTestWithTransactions
+ class Unit < MiniTestWithHooks::Unit
+ include TestSetupHelper
+
+ def before_suites
+ super
+ setup_nested_transactions
+ # load any data we want available for all tests
+ end
+
+ def after_suites
+ teardown_nested_transactions
+ super
+ end
+ end
+ end
+
+ MiniTest::Unit.runner = MiniTestWithTransactions::Unit.new
+
+== FAQ
+
+=== How to test SimpleDelegates?
+
+The following implementation and test:
+
+ class Worker < SimpleDelegator
+ def work
+ end
+ end
+
+ describe Worker do
+ before do
+ @worker = Worker.new(Object.new)
+ end
+
+ it "must respond to work" do
+ @worker.must_respond_to :work
+ end
+ end
+
+outputs a failure:
+
+ 1) Failure:
+ Worker#test_0001_must respond to work [bug11.rb:16]:
+ Expected #<Object:0x007f9e7184f0a0> (Object) to respond to #work.
+
+Worker is a SimpleDelegate which in 1.9+ is a subclass of BasicObject.
+Expectations are put on Object (one level down) so the Worker
+(SimpleDelegate) hits `method_missing` and delegates down to the
+`Object.new` instance. That object doesn't respond to work so the test
+fails.
+
+You can bypass `SimpleDelegate#method_missing` by extending the worker
+with `MiniTest::Expectations`. You can either do that in your setup at
+the instance level, like:
+
+ before do
+ @worker = Worker.new(Object.new)
+ @worker.extend MiniTest::Expectations
+ end
+
+or you can extend the Worker class (within the test file!), like:
+
+ class Worker
+ include ::MiniTest::Expectations
+ end

+
+== REQUIREMENTS:
+
+* Ruby 1.8, maybe even 1.6 or lower. No magic is involved.
+
+== INSTALL:
+
+ sudo gem install minitest
+
+On 1.9, you already have it. To get newer candy you can still install
+the gem, but you'll need to activate the gem explicitly to use it:
+
+ require 'rubygems'
+ gem 'minitest' # ensures you're using the gem, and not the built in MT
+ require 'minitest/autorun'
+
+ # ... usual testing stuffs ...
+
+DO NOTE: There is a serious problem with the way that ruby 1.9/2.0
+packages their own gems. They install a gem specification file, but
+don't install the gem contents in the gem path. This messes up
+Gem.find_files and many other things (gem which, gem contents, etc).
+
+Just install minitest as a gem for real and you'll be happier.
