Fix

⚠️ This project is still in the experimental phase. May be used at your own risk.

Project goals

Extract specs from the tests.
Look like English documents.
Be minimalist and easy to use.
Run tests quickly.

Installation

Add this line to your application's Gemfile:

gem "fix", ">= 1.0.0.beta8"

And then execute:

bundle

Or install it yourself as:

gem install fix --pre

Example

Given these specifications:

# examples/duck/fix.rb

require "fix"

Fix :Duck do
  it SHOULD be_an_instance_of :Duck

  on :swims do
    it MUST be_an_instance_of :String
    it MUST eql "Swoosh..."
  end

  on :speaks do
    it MUST raise_exception NoMethodError
  end

  on :sings do
    it MAY eql "♪... ♫..."
  end
end

When we load this Duck application:

# examples/duck/app.rb
class Duck
  def walks
    "Klop klop!"
  end

  def swims
    "Swoosh..."
  end

  def quacks
    puts "Quaaaaaack!"
  end
end

And we run this test:

# examples/duck/test.rb

require_relative "app"
require_relative "fix"

Fix[:Duck].against { Duck.new }

ruby examples/duck/test.rb

We should see this output:

(irb):3 Success: expected #<Duck:0x00007fb2fa208708> to be an instance of Duck.
(irb):7 Success: expected to eq "Swoosh...".
(irb):15 NoMethodError: undefined method `sings' for #<Duck:0x00007fb2fd8371d0>.
(irb):6 Success: expected "Swoosh..." to be an instance of String.
(irb):11 Success: undefined method `speaks' for #<Duck:0x00007fb2fcc79258>.
