# frozen_string_literal: true
# FakeFS::SpecHelpers provides a simple macro for RSpec example
# groups to turn FakeFS on and off.
# To use it simply require 'fakefs/spec_helpers', then include
# FakeFS::SpecHelpers into any example groups that you wish
# to use FakeFS in. For example:
#
# require 'fakefs/spec_helpers'
#
# describe "Some specs that deal with files" do
# include FakeFS::SpecHelpers
# ...
# end
#
# By default, including FakeFS::SpecHelpers will run for each
# example inside a describe block.
# If you want to turn on FakeFS one time only for all your examples,
# you will need to include FakeFS::SpecHelpers::All.
#
# Alternatively, you can include FakeFS::SpecHelpers in all your
# example groups using RSpec's configuration block in
# your spec helper:
#
# require 'fakefs/spec_helpers'
#
# RSpec.configure do |config|
# config.include FakeFS::SpecHelpers
# end
#
# If you do the above then use_fakefs will be available in all of
# your example groups.
#
require 'fakefs/safe'
# FakeFS module
module FakeFS
def use_fakefs(describe_block, opts)
describe_block.before opts[:with] do
FakeFS.activate!
end
describe_block.after opts[:with] do
FakeFS.deactivate!
FakeFS::FileSystem.clear if opts[:with] == :each
end
end
# Module SpecHelpers
module SpecHelpers
include ::FakeFS
def self.extended(example_group)
example_group.use_fakefs(example_group, with: :each)
end
def self.included(example_group)
example_group.extend self
end
# Module All
module All
include ::FakeFS
def self.extended(example_group)
example_group.use_fakefs(example_group, with: :all)
end
def self.included(example_group)
example_group.extend self
end
end
