如何使用Rails和minitest模拟OmniAuth哈希? [英] How do I mock an OmniAuth hash using Rails and minitest?

问题描述

我正在使用带有minitest的Rails 5.我想模拟登录到会话控制器的会话，该控制器依赖于omniauth(我使用Google和FB进行登录).我的控制器测试中有这个，test/controllers/rates_controller_test.rb，

I'm using Rails 5 with minitest. I want to mock logging into my sessions controller, which relies on omniauth (I use Google and FB for login). I have this in my controller test, 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

然后我尝试在测试助手test/test_helper.rb

and then I try and set up login in my test helper, 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，当我运行控制器测试时，在我的会话控制器中评估此行时，我得到一个nil值...

However, when I run my controller test, I'm getting a nil value when this line is evaluated in my sessions controller ...

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

上面，'env ["omniauth.auth"]'计算为nil.

Above, 'env["omniauth.auth"]' is evaluating to nil.

推荐答案

OmniAuth文档状态

当您尝试测试OmniAuth时，您需要设置两个环境变量

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

并提供使用RSpec的示例

and provide examples using RSpec

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

根据您的情况，似乎您可能需要设置

In your case, it seems like you may need to set

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

调用OmniAuth.config.add_mock之后，在setup_omniauth_mock方法中

.

in your setup_omniauth_mock method, after the call to OmniAuth.config.add_mock.
