Initialize mocks with allowed calls

Scenarios

mock allows the predefined calls and returns value

Given

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

RSpec.define_role 'Fetcher' do
  def fetch(id) end
end

And

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

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

Given

a file named "lib/user.rb" with:

class User < Struct.new(:fetcher)
  def favorite_artist
    fetcher.fetch(1)
  end
end

And

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

require 'spec_helper'
require 'user'
require 'roles/fetcher'

RSpec.describe User, '#suspend!' do
  it 'notifies the console' do
    expected = 'Theolonious Monk'
    fetcher = role_double("Fetcher", fetch: expected)
    user = User.new(fetcher)

    actual = user.favorite_artist

    expect(actual).to eq expected
  end
end

When

I run rspec spec/user_spec.rb

Then

the example should pass
