我试图存根代码中的方法：

def create
  @user = Xaaron::User.new(user_signup_params)
  if save_new_user(@user)
    user = User.find(@user.first_name.parameterize)
    user_info_to_publish = {user_name: user.user_name, first_name: user.first_name, auth_token: user.auth_token, email: user.email}
    response = Xaaron::Publishers::Users.publish_new_user(user_info_to_publish)

    if response == 200
      user.set_published_user(true, false, 'create')
      redirect_to login_path
    else
      user.set_published_user(false, true, 'create')
      flash[:error] = 'Something went wrong in publishing your information to the applications you can interact with. We are aware of the issue and are on it.'
      redirect_to login_path
    end
  else
    render :new
  end
end

有问题的方法是Xaaron::Publishers::Users.publish_new_user(user_info_to_publish)我需要对这个方法进行存根，以便可以检查以确保一切正常。

有问题的测试是：

it "should create a new user" do
  expect(Xaaron::Publishers::Users).to receive(:publish_new_user).with(
    {first_name: @user.first_name, user_name: 'johnq', email: @user.email, auth_token: @user.auth_token}
  ).and_return nil

  post :create, user: {
    first_name: @user.first_name, user_name: 'johnq',
    email: @user.email, email_confirmation: @user.email,
    password: 'SamplePassword', password_confirmation: 'SamplePassword'
  }

  expect(response).to redirect_to login_path
end

由于一件事，该测试将失败auth_token。我已将其设置为在数据库中设置用户之前生成的。将@user通过完成：@user = FactoryGirl.build(:user)

我将如何更改测试以使其通过？

更新

我应该包括以下内容：

测试失败，因为：

  Xaaron::Publishers::Users received :publish_new_user with unexpected arguments
         expected: ({:first_name=>"Adam", :user_name=>"johnq", :email=>"[email protected]"})
              got: ({:user_name=>"johnq", :first_name=>"Adam", :auth_token=>"KrGN3zu3kQJQdyh8JHl_XA", :email=>"[email protected]", :auth_token=>nil})
