Test::Unit::Context
¶ ↑
Makes Test::Unit::TestCase
'context-able' and thus (subjectively - hopefully) much easier to read and write. If you have ever seen RSpec than it's the very same context do … end re-invented for Test::Unit.
Inspired by gem ‘context’ that does the same for the good 'old' test-unit 1.2.3 bundled with Ruby 1.8.x standard libraries.
Installation¶ ↑
Add it to your application's Gemfile (along with test-unit) e.g. :
group :test do gem 'test-unit' gem 'test-unit-context' end
Or install it yourself, if you're not using Bundler :
$ gem install test-unit-context
Usage¶ ↑
class ChuckNorrisTest < Test::Unit::TestCase setup do @subject = ChuckNorris.new end test "can be divided by zero" assert_equal @subject * 2, @subject / 0 end context 'frozen' do setup { @subject.freeze } test "won't answer" do assert_raise NoMemoryError do @subject.frozen? end end test "sqrt works" assert_nothing_raised do Math.sqrt -2 end end end shared 'elementary math facts' do test "square root is rational" assert_kind_of Rational, Math.sqrt(@subject) end test "greater than infinity" assert @infinity < @subject end private setup def create_infinity @infinity = 1 / 0.0 end end uses 'elementary math facts' context 'cloned' do setup do @subject = @subject.clone end test 'is Arnold Schwarzenegger' do assert_instance_of Terminator, @subject assert_nil @subject.is_a?(ChuckNorris) end like 'elementary math facts' end end
Spec Mode¶ ↑
require 'test/unit/context/spec' describe ChuckNorris, '#fart' do setup do @subject = ChuckNorris.new @subject.fart end it "creates a parallel universe" do assert Object.const_defined?(:Universe) assert_equal @subject, Universe.instance assert_empty ObjectSpace.each_object(Universe).to_a end end # NOTE: do not try running this at home!
