Defekt

A micro testing framework.

Installation

Add this line to your application's Gemfile:

gem 'defekt'

And then execute:

$ bundle

Or install it yourself as:

$ gem install defekt

Usage

Inherit your test classes from Defekt::Base and define your tests prefixed with test_. You can define before and after methods, which are invoked around each test.

require 'defekt'

class Person
  attr_reader :name

  def initialize(name)
    @name = name
  end
end

class PersonTest < Defekt::Base
  def before
    @person = Person.new('kodnin')
  end

  def test_initialize
    instance_of! Person, @person
  end

  def test_name
    equal_to! 'kodnin', @person.name
  end

  def test_age
    not_respond_to! @person, :age
    @person.stub(:age, 'unknown') do
      respond_to! @person, :age
      equal_to! 'unknown', @person.age
    end
  end
end

Defekt.run

Assertions

All available assertions have negative counterparts prefixed with not_.

• true!
• equal_to!
• identical_to!
• included_in!
• instance_of!
• kind_of!
• respond_to!

You can add your own assertions by opening up the Defekt::Assertions module.

module Defekt
  module Assertions
    def awesome!(value)
      unless value == 'awesome'
        raise Errors::AwesomeError, "~#{value}~ is not awesome"
      end
    end
  end
end

Development

After checking out the repo, run bin/setup to install dependencies. Then, run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release to create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
