Tunit

tunit is my take on building a testing framework, it's heavily influenced by minitest.

NOTE This is very unstable and is just a playground for my ideas.

Since this is heavily influenced by Ryan Davis' minitest there are a lot of similarities between the two frameworks.

I wanted to see how much code and effort are needed to build a testing framework of my own, while looking at the learnings of minitest.

Usage

Unit

I personally love TDD frameworks like minitest, so I tried to mimic their behaviour and patterns as close as I possibly could. As with minitest, this is just plain ruby.

class BlahTest < Tunit::Test
  def setup
    self.blah = Blah.new
  end
  attr_accessor :blah

  def test_the_answer_to_everything
    assert_equal 42, blah.the_ultimate_answer
  end

  def test_packing_list
    assert_includes blah.packing_list, "towel"
  end

  def test_that_will_be_skipped
    skip "test this later"
  end
end

What's important to me is that BlahTest is just a simple subclass, and test_the_answer_to_everything is a simple method. Assertions and lazily-loaded variables are just methods, everything is just a simple method definition away.

I'm a strong believer in that you should only mock and stub things so you can assert on something else. That's why a test-method must have assertions in tunit

class EmptyTest < Tunit::Test
  def test_im_going_to_fail
  end

  def test_so_will_i
    1 + 1 == 2
  end
end

Spec

There is also a small Spec DSL that follows along with tunit

require 'tunit/autorun'

Example = Class.new

describe Example do
  describe 'passing tests' do
    it 'even' do
      assert 2.even?
    end

    it 'passed once more' do
      assert_includes [1, 2], 2
    end
  end

  describe 'failing tests' do
    it 'fails on empty tests' do
    end

    it 'fails hard' do
      refute 2.even?
    end
  end

  describe 'skipps' do
    it 'skippedy skip' do
      skip
    end

    it 'skips with a message' do
      skip 'here!'
    end
  end
end

That's it, no magic let's or subjects. Just it and describe blocks
