Playing multiple roles

Given

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

require 'rspec/role-mocks'
$LOAD_PATH.unshift('lib')

And

a file named "spec/roles/logger.rb" with:

RSpec.define_role 'Logger' do
  def log(message); end
end

And

a file named "spec/roles/writer.rb" with:

RSpec.define_role 'Writer' do
  def write(message, opts); end
end

And

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

require 'spec_helper'
require 'console_logger'
require 'roles/logger'
require 'roles/writer'

describe ConsoleLogger do
  it_plays_role 'Logger'
  it_plays_role 'Writer'
end

Then

the example should pass
