问使用MiniTest时，当尝试测试``omniauth Google-oauth2‘gem时，我一直得到一个302重定向到我的sign_in路径

EN

Rails.application.routes.draw do

  devise_for :users, controllers: { omniauth_callbacks: "users/omniauth_callbacks" }

  devise_scope :user do
      get 'sign_in', :to => 'devise/sessions#new', :as => :new_user_session
      get 'sign_out', :to => 'devise/sessions#destroy', :as => :destroy_user_session
    end

  root to: "home#index"

    OmniAuth.config.test_mode = true
      OmniAuth.config.mock_auth[:google_oauth2] = OmniAuth::AuthHash.new({

    setup_omniauth_mock(user)
    get user_google_oauth2_omniauth_authorize_path
