Use fixtures in your tests

Sometimes your tests need existing files to work - e.g binary data files you
cannot create programmatically. Since aruba >= 0.6.3 includes some basic
support for fixtures. All you need to do is the following:

  1. Create a fixtures-directory
  2. Create fixture files in this directory
Background
Given
I use a fixture named "cli-app"
Scenarios
  1. Use a fixture for your tests
  2. Use a fixture for your tests in test/
  3. Use a fixture for your tests in spec/
  4. Use a fixture for your tests in features/
Use a fixture for your tests
Given
a file named "features/fixtures.feature" with: 
Feature: Fixture
  Scenario: Fixture
    Given a file named "fixtures_spec.rb" with:
    """
    RSpec.describe 'My Feature' do
      describe '#read_music_file' do
        context 'when the file exists' do
          before :each { copy '%/song.mp3', 'file.mp3' }

          it { expect('file.mp3').to be_an_existing_file }
        end
      end
    end
    """
And
a directory named "fixtures"
And
an empty file named "fixtures/fixtures-app/test.txt"
When
I run rspec
Then
the specs should all pass
Use a fixture for your tests in test/
Given
a file named "features/fixtures.feature" with:
