ariete-rspec

An extension of Ariete for RSpec. You can test standard output with RSpec custom matchers, eg. be_output, be_output_to_stderr.

Requirement

• Ruby 2.0 or hight
• RSpec 3

Installation

$ (sudo) gem install 'ariete-rspec'

Usage

klass.rb

class Klass
  class << self
    def output_out
      puts "Ariete is a kind of rabbit."
    end

    def output_err
      warn "Ariete means 'Lop' in Italian."
    end
  end
end

klass_spec.rb

require "ariete-rspec"
require_relative "klass"

RSpec.describe Klass do
  # Ariete extends matchers of RSpec.
  # Therefore, you can use 'be_output' and 'be_output_to_stderr'.
  describe ".output_out" do
    subject { Klass.method(:output_out).to_proc }
    it { is_expected.to be_output "Ariete is a kind of rabbit.\n" }
  end

  describe ".output_out (an alternate expression)" do
    subject { -> { Klass.output_out } }
    it { is_expected.to be_output "Ariete is a kind of rabbit.\n" }
  end

  describe ".output_err" do
    subject { Klass.method(:output_err).to_proc }
    it { is_expected.to be_output_to_stderr "Ariete means 'Lop' in Italian.\n" }
  end

  describe ".output_err (an alternate expression)" do
    subject { -> { Klass.output_err } }
    it { is_expected.to be_output_to_stderr "Ariete means 'Lop' in Italian.\n" }
