Используя MiniTest, при попытке проверить гем `omniauth-google-oauth2` я получаю перенаправление 302 на мой путь к sign_in

Question

Я установил omniauth-google-oauth2 гем с моим приложением rails. И это работает, но пока я пытаюсь написать свой тест, я продолжаю перенаправлять 302. Во многих результатах веб-сайта, которые я видел, упоминалось, как протестировать его в Rspec, но я пытаюсь сделать это с помощью MiniTest, который поставляется с Rails. Так как я новичок в этом, я изо всех сил пытаюсь увидеть, где я все испортил.

routes.rb

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"

end

test_helper.rb

ENV['RAILS_ENV'] ||= 'test'
require_relative '../config/environment'
require 'rails/test_help'
require 'mocha/minitest'

class ActiveSupport::TestCase
  # Setup all fixtures in test/fixtures/*.yml for all tests in alphabetical order.
  fixtures :all

  def setup_omniauth_mock(user)
    OmniAuth.config.test_mode = true
      OmniAuth.config.mock_auth[:google_oauth2] = OmniAuth::AuthHash.new({
        provider: "google_oauth2",
        email: "#{user.email}",
        first_name: "#{user.first_name}",
        last_name: "#{user.last_name}"
      })
      Rails.application.env_config["devise.mapping"] = Devise.mappings[:user]
    Rails.application.env_config["omniauth.auth"] = OmniAuth.config.mock_auth[:google_oauth2]
  end

  def login_with_user(user)
    setup_omniauth_mock(user)
    get user_google_oauth2_omniauth_authorize_path
  end

end

module ActionController
    class TestCase
        include Devise::Test::ControllerHelpers
    end
end

module ActionDispatch
    class IntegrationTest
        include Devise::Test::IntegrationHelpers
    end
end

тест / интеграция / login_with_google_oauth2_test.rb

require 'test_helper'

class LoginWithGoogleOauth2Test < ActionDispatch::IntegrationTest
  setup do
    @user = users(:one)
  end

  test "allows a logged-in user to view the home page" do 
    login_with_user(@user)
    get root_path
    assert_redirected_to root_path
    assert_selector "h1", text: "#{user.full_name}"
  end

end

Answer 1

Итак, я смог найти способ тестирования omniauth-google-oauth2. Я сделаю все возможное, чтобы показать это ниже. Спасибо всем, кто нашел время, чтобы разобраться в моем вопросе.

тест \ интеграция \ authorization_integration_test.rb

require 'test_helper'

class AuthorizationIntegrationTest < ActionDispatch::IntegrationTest
  include Capybara::DSL
  include Capybara::Minitest::Assertions
  include Devise::Test::IntegrationHelpers

    setup do
        OmniAuth.config.test_mode = true
        Rails.application.env_config["devise.mapping"] = Devise.mappings[:user]
        Rails.application.env_config["omniauth.auth"]  = google_oauth2_mock
    end

    teardown do
        OmniAuth.config.test_mode = false
    end

    test "authorizes and sets user currently in database with Google OAuth" do
        visit root_path
        assert page.has_content? "Sign in with Google"  
        click_link "Sign in with Google"
        assert page.has_content? "Successfully authenticated from Google account."
    end

    private

        def google_oauth2_mock
            OmniAuth.config.mock_auth[:google_oauth2] = OmniAuth::AuthHash.new({
            provider: "google_oauth2",
            uid: "12345678910",
            info: { 
                email: "fakeemail@gmail-fake.com",
                first_name: "David",
                last_name: "McDonald"
            },
            credentials: {
                token: "abcdefgh12345",
                refresh_token: "12345abcdefgh",
                expires_at: DateTime.now
            }
          })
        end

end
