Minitest Mario A Chávez @mario_chavez
¿Quién prueba sus aplicaciones?
¿Quién prueba sus aplicaciones de forma automática?
- Test::Unit - RSpec -Minitest
Incluido como librería estándar desde Ruby 1.9
Test::Unit es historia, Minitest es compatible
Rspec bloated!
Minitest es pequeño y rápido, fácil de extender
Minitest es Ruby!
require 'minitest/autorun' class TeaTest < Minitest::Test def test_green_tea_temperature hot_tea =
Tea.new :green assert(hot_tea.temperature == 150) end end
require 'minitest/autorun' class TeaTest < Minitest::Test def test_green_tea_temperature hot_tea =
Tea.new :green assert_equal 150, hot_tea.temperature end end
Pero me gusta mas la sintaxis Spec!
require 'minitest/autorun' describe Tea do describe ‘Green tea’ do subject
{ Tea.new :green } it ‘temperature should be right’ do subject.temperature.must_equal 150 end end end
¿Qué? ¿doble “describe”? Vamos a extender Minitest
class Minitest::Spec class << self alias :context :describe end end
require 'minitest/autorun' describe Tea do context ‘Green tea’ do subject
{ Tea.new :green } it ‘temperature should be right’ do subject.temperature.must_equal 150 end end end
Matchers personalizados
require 'minitest/assertions' module Minitest::Assertions def assert_include(expected, actual) expected.is_a?(Enumerable) && expected.include?(actual)
end end require 'minitest/autorun' class TeaTest < Minitest::Test def test_available_teas_include_green teas = [:camomille, :green] assert_include teas, :green end end
require 'minitest/spec' module Minitest::Expectations Enumerable.infect_an_assertion :assert_inclu de, :must_include end require
'minitest/autorun' describe Tea do it 'available teas include green' do teas = [:camomile, :green] teas.must_include :green end end
Múltiples reporters
$ ruby minitest.rb -v Run options: -v --seed 58567 #
Running tests: Tea::Green tea#test_0001_temperature should be right = 0.00 s = . TeaTest#test_green_tea_temperature = 0.00 s = . Finished tests in 0.000986s, 2028.3976 tests/s, 2028.3976 assertions/s. 2 tests, 2 assertions, 0 failures, 0 errors, 0 skips
$ ruby minitest.rb Run options: --seed 36590 # Running: .
Finished in 0.001162s, 860.5852 runs/s, 0.0000 assertions/s. $ ruby minitest.rb -p Run options: -p --seed 8992 # Running: . Fabulous run in 0.001219s, 820.3445 runs/ s, 0.0000 assertions/s.
Minitest ejecuta las pruebas de forma aleatoria
También las puede ejecutar de forma paralela
Incluye: - Benchmark - Mocks -Stubs
Rails 4 usa Minitest con sintaxis de Test::Unit
