Oktobertest

Small test library.

Why?

This is a project I started over the weekend. I was looking at Cutest and I thought: "It shouldn't be so difficult to make a test library".

Features

• Setup - Test - Teardown model.
• Each test is an instance of Oktobertest::Test, which means that each test runs its own context.
• Each scope is an instance of Oktobertest::Scope. Methods defined in a scope are copied into each test it contains.
• Extensible: it's easy to add more assertions (See oktobertest-contrib).

Installation

Add this line to your application's Gemfile:

gem 'oktobertest', group: :test
# or this if you want to use oktobertest master
# gem 'oktobertest', group: :test, github: 'patriciomacadden/oktobertest'

And then execute:

$ bundle

Or install it yourself as:

$ gem install oktobertest

Usage

Example

scope do
  setup do
    @foo = 'foo'
  end

  test 'this test will pass' do
    assert @foo == 'foo'
  end

  test 'this test will pass too' do
    assert_raises RuntimeError do
      raise RuntimeError
    end
  end

  test 'this test will fail' do
    flunk 'fail!'
  end

  test 'skip this one!' do
    skip
  end
end

Assertions

For now there are 2 assertions:

• assert: fails unless the given condition is true.
• assert_raises: fails unless the given block raises the given exception.

And there is a way of making tests fail (flunk) and skipping them (skip).

How to add assertions?

That's quite simple. Just define them in the Oktobertest::Assertions module:

module Oktobertest
  module Assertions
    def assert_equal(expected, actual, message = nil)
      message ||= "#{expected.inspect} is not equal to #{actual.inspect}"
      assert expected == actual, message
    end
  end
end

Running a test suite

You can run a test suite using rake or ruby.

Using rake:

require 'rake/testtask'

Rake::TestTask.new do |t|
  t.libs << 'test'
  t.pattern = 'test/*_test.rb'
end

task default: :test

Using ruby:

$ ruby -r oktobertest test/*_test.rb

When using ruby directly, you can specify the scope (S) or the test (T) to run:

$ T='test this' ruby -r oktobertest test/*_test.rb

Testing Rack applications

Pretty simple:

require 'rack/test'

module Oktobertest
  class Test
    include Rack::Test::Methods

    def app
      Proc.new { |env| [200, {}, ['hello world']] }
    end
  end
end

scope 'rack app' do
  test 'GET /' do
    get '/'
    assert last_response.status == 200
  end
end
