Feature: Extract text from output

  If you need to strip down some command output to plain text, you can use the
  `#extract_text`-method for this.

  Background:
    Given I use a fixture named "cli-app"

  Scenario: Output contains ansi escape codes prefixed by \e
    Given an executable named "bin/aruba-test-cli" with:
    """
    #!/bin/bash
    echo -n "\e[31mText"
    """
    And a file named "spec/extract_text_spec.rb" with:
    """
    require 'spec_helper'

    RSpec.describe 'Run command', :type => :aruba do
      before(:each) { run('cli') }
      before(:each) { stop_all_commands }

      it { expect(extract_text(unescape_text(last_command.output))).to eq "Text" }
    end
    """
    When I run `rspec`
    Then the specs should all pass
