Check if path exists and is file

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

require 'spec_helper'

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

  it { expect(file).to be_an_existing_file }
end

Background

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

Scenarios

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

Expect single existing file

Given

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

require 'spec_helper'

RSpec.describe 'Check if file exists and is file', :type => :aruba do
  let(:file) { 'file.txt' }
  before(:each) { touch(file) }
  it { expect(file).to be_an_existing_file }
end

When

I run rspec

Then

the specs should all pass

Expect single non-existing file

Given

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

require 'spec_helper'

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

When

I run rspec

Then

the specs should all pass

Expect multiple existing files

Given

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

require 'spec_helper'

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

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

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

When

I run rspec

Then

the specs should all pass

Expect a least one existing file

Given

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

require 'spec_helper'

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

  before :each do
    touch(files.first)
  end

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

When

I run rspec

Then

the specs should all pass
