如何使用 Rails 和 minitest 模拟 OmniAuth 散列?

How do I mock an OmniAuth hash using Rails and minitest?

我正在使用 Rails 5 和 minitest。我想模拟登录到我的会话控制器,它依赖于 omniauth(我使用 Google 和 FB 进行登录)。我在我的控制器测试中有这个,test/controllers/rates_controller_test.rb,

 class RatesControllerTest < ActionDispatch::IntegrationTest

  # Login the user
  def setup
    logged_in_user = users(:one)
    login_with_user(logged_in_user)
  end

然后我尝试在我的测试助手中设置登录,test/test_helper.rb,

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_hash = { 'provider' => 'google',
                      'uid' => '12345',
                      'info' => {
                         'name' => "#{user.first_name} #{user.last_name}",
                          'email' => user.email,
                      },
                      'extra' => {'raw_info' =>
                                      { 'location' => 'San Francisco',
                                        'gravatar_id' => '123456789'
                                      }
                      }
    }

    OmniAuth.config.add_mock(:google, omniauth_hash)
  end

  # Add more helper methods to be used by all tests here...
  def login_with_user(user)
    setup_omniauth_mock(user)
    post sessions_path
  end

但是,当我 运行 我的控制器测试时,当在我的会话控制器中评估此行时,我得到一个 nil 值 ...

user = User.from_omniauth(env["omniauth.auth"])

以上,'env["omniauth.auth"]' 的计算结果为零。

OmniAuth docs状态

When you try to test the OmniAuth, you need to set two env variables

并使用 RSpec

提供示例
before do
  Rails.application.env_config["devise.mapping"] = Devise.mappings[:user] # If using Devise
  Rails.application.env_config["omniauth.auth"] = OmniAuth.config.mock_auth[:twitter]
end

在你的情况下,你可能需要设置

Rails.application.env_config["omniauth.auth"] = OmniAuth.config.mock_auth[:google]

在您的 setup_omniauth_mock 方法中,在调用 OmniAuth.config.add_mock 之后。
