Check if path exists

If you need to check if a given path exists, you can use the
be_an_existing_path-matcher. It doesn't care if the path is a directory or
a path.

require 'spec_helper'

RSpec.describe 'Check if path exists', :type => :aruba do
  let(:path) { 'file.txt' }
  before(:each) { touch(path) }

  it { expect(path).to be_an_existing_path }
end
Background
Given
I use a fixture named "cli-app"
Scenarios
  1. Expect single existing path
  2. Expect single existing directory
  3. Expect single non-existing path
  4. Expect multiple existing paths
  5. Expect a least one existing path
Expect single existing path
Given
a file named "spec/existing_path_spec.rb" with: 
require 'spec_helper'

RSpec.describe 'Check if path exists', :type => :aruba do
  let(:path) { 'file.txt' }
  before(:each) { touch(path) }
  it { expect(path).to be_an_existing_path }
end
When
I run rspec
Then
the specs should all pass
Expect single existing directory
Given
a file named "spec/existing_path_spec.rb" with: 
require 'spec_helper'

RSpec.describe 'Check if path exists', :type => :aruba do
  let(:path) { 'dir.d' }
  before(:each) { create_directory(path) }
  it { expect(path).to be_an_existing_path }
end
When
I run rspec
Then
the specs should all pass
Expect single non-existing path
Given
a file named "spec/existing_path_spec.rb" with: 
require 'spec_helper'

RSpec.describe 'Check if path exists', :type => :aruba do
  let(:path) { 'file.txt' }
  it { expect(path).not_to be_an_existing_path }
end
When
I run rspec
Then
the specs should all pass
Expect multiple existing paths
Given
a file named "spec/existing_path_spec.rb" with: 
require 'spec_helper'

RSpec.describe 'Check if path exists', :type => :aruba do
  let(:paths) { %w(path1.txt path2.txt) }

  before :each do
    paths.each { |f| touch(f) }
  end

  it { expect(paths).to all be_an_existing_path }
end
When
I run rspec
Then
the specs should all pass
Expect a least one existing path
Given
a file named "spec/existing_path_spec.rb" with: 
require 'spec_helper'

RSpec.describe 'Check if path exists', :type => :aruba do
  let(:paths) { %w(path1.txt path2.txt) }

  before :each do
    touch(paths.first)
  end

  it { expect(paths).to include an_existing_path }
end
When
I run rspec
Then
the specs should all pass
