Question

正如受试者所说。似乎实现的代码总是create一个新的记录而不是现有的记录。

这是我的rspec测试代码：

describe "#from_facebook" do 
  it "return existing related user" do 
    existing_user = FactoryGirl.create(:user)
    user_from_facebook = User.from_facebook({ uid: existing_user.uid })
    expect(user_from_facebook.email).to eql existing_user.email
  end
end

这是测试实现：

def self.from_facebook(fb_auth)
where(provider: "facebook", uid: fb_auth[:uid]).first_or_create do |user|
    user.email = fb_auth[:email]
    user.password = Devise.friendly_token[0, 20]
  end
end

我总是这样：

1) User#from_facebook return existing related user
 Failure/Error: expect(user_from_facebook.email).to eql existing_user.email

   expected: "karolann.gulgowski@satterfield.us"
        got: nil

   (compared using eql?)
 # ./spec/models/user_spec.rb:48:in `block (3 levels) in <top (required)>'

以下是通过puts的控制台结果。 existing_user：

#<User id: 105, email: "karolann.gulgowski@satterfield.us", encrypted_password: "$2a$04$90uzEdbwfnqfUL0CDhNOH.THUbzovFyJK1OPg7VcgxL...", reset_password_token: nil, reset_password_sent_at: nil, remember_created_at: nil, sign_in_count: 0, current_sign_in_at: nil, last_sign_in_at: nil, current_sign_in_ip: nil, last_sign_in_ip: nil, created_at: "2015-08-30 04:12:59", updated_at: "2015-08-30 04:12:59", auth_token: "vkvm2-fLe5x1dZGbewqw", provider: nil, uid: "133290925">

代表user_from_facebook：

#<User id: nil, email: nil, encrypted_password: "$2a$04$lxdBWBsXY4febfgurgHJKOdNcOMCuQQO2DHshWChnxA...", reset_password_token: nil, reset_password_sent_at: nil, remember_created_at: nil, sign_in_count: 0, current_sign_in_at: nil, last_sign_in_at: nil, current_sign_in_ip: nil, last_sign_in_ip: nil, created_at: nil, updated_at: nil, auth_token: "", provider: "facebook", uid: "133290925">

请告诉我这里有什么问题。提前谢谢。

Answer 1

您的User工厂未完全设置用户。它会创建以下user对象：

#<User id: 105,
       email: "karolann.gulgowski@satterfield.us",
       encrypted_password: "$2a$04$90uzEdbwfnq...",
       reset_password_token: nil,
       reset_password_sent_at: nil,
       remember_created_at: nil,
       sign_in_count: 0,
       current_sign_in_at: nil,
       last_sign_in_at: nil,
       current_sign_in_ip: nil,
       last_sign_in_ip: nil,
       created_at: "2015-08-30 04:12:59",
       updated_at: "2015-08-30 04:12:59",
       auth_token: "vkvm2-fLe5x1dZGbewqw",
       provider: nil,
       uid: "133290925"

请注意，提供商为nil。因此，您的from_facebook方法（查找提供商的uuid 和）无法找到该用户。

作为解决方案，请使用以下内容在规范中创建existing_user：

existing_user = FactoryGirl.create(:user, provider: 'facebook')

Answer 2

您是否在uid设置了FactoryGirl.create(:user)？

您可以发布user工厂的内容吗？您可能想要创建一个设置唯一facebook_user

的uid工厂

Rspec测试总是因类方法而失败
