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.
