Overview

FakeFS::SpecHelpers provides a simple macro for RSpec example groups to turn FakeFS on and off. To use it need to require ‘fakefs/safe’ and ‘fakefs/spec_helpers’. Then include FakeFS::SpecHelpers into any example groups that you wish to use FakeFS in. The “use_fakefs” macro is then available to install before and after hooks which will enable and disable FakeFS. For example:

describe SomeClassThatDealsWithFiles
  include FakeFS::SpecHelpers
  use_fakefs
  ...
end

Alternatively, you can include FakeFS::SpecHelpers in all your example groups using RSpec’s configuration block in your spec helper:

require 'fakefs/safe'
require 'fakefs/spec_helpers'
require 'fakefs/spec_helpers'
Spec::Runner.configure do |config|
  config.extend FakeFS::SpecHelpers
end
