Check if path exists and is an executable file

If you need to check if a given path exists and is a file, you can use the
be_an_existing_executable-matcher.

require 'spec_helper'

RSpec.describe 'Check if file exists and is an executable file', :type => :aruba do
  let(:file) { 'file.txt' }
  before(:each) { touch(file) }
  before(:each) { chmod(0755, file) }

  it { expect(file).to be_an_existing_executable }
end

Background

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

Scenarios

Expect single existing executable file
Expect single non-existing executable file
Expect multiple existing executable files
Expect a least one existing executable file

Expect single existing executable file

Given

a file named "spec/existing_executable_spec.rb" with:

require 'spec_helper'

RSpec.describe 'Check if file exists and is an executable file', :type => :aruba do
  let(:file) { 'file.txt' }
  before(:each) { touch(file) }
  before(:each) { chmod(0755, file) }

  it { expect(file).to be_an_existing_executable }
end

When

I run rspec

Then

the specs should all pass

Expect single non-existing executable file

Given

a file named "spec/existing_executable_spec.rb" with:

require 'spec_helper'

RSpec.describe 'Check if file exists and is an executable file', :type => :aruba do
  let(:file) { 'file.txt' }
  it { expect(file).not_to be_an_existing_executable }
end

When

I run rspec

Then

the specs should all pass

Expect multiple existing executable files

Given

a file named "spec/existing_executable_spec.rb" with:

require 'spec_helper'

RSpec.describe 'Check if file exists and is an executable file', :type => :aruba do
  let(:files) { %w(file1.txt file2.txt) }

  before :each do
    files.each do |f|
      touch(f)
      chmod(0755, f)
    end
  end

  it { expect(files).to all be_an_existing_executable }
end

When

I run rspec

Then

the specs should all pass

Expect a least one existing executable file

Given

a file named "spec/existing_executable_spec.rb" with:

require 'spec_helper'

RSpec.describe 'Check if file exists and is an executable file', :type => :aruba do
  let(:files) { %w(file1.txt file2.txt) }

  before :each do
    touch(files.first)
    chmod(0755, files.first)
  end

  it { expect(files).to include an_existing_executable }
end

When

I run rspec

Then

the specs should all pass
