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"

Scenarios

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

Output contains ansi escape codes prefixed by \033
