从初始化属性切换到Factory时，rspec测试失败 [英] rspec test failure when switching from initializing attributes to Factory
问题描述
这对我来说毫无意义，希望有人可以提供帮助.使用工厂创建用户时，我遇到一个测试失败(看似相似的测试通过).
This makes no sense to me, hope someone can help. I'm getting a single test failure when creating a user using a factory (seemingly similar tests pass).
在我的user_spec.rb测试文件中，该用户最初是这样创建的.使用这种初始化方法，所有测试都会通过.
In my user_spec.rb test file, the user was originally created like this. Using this initialization approach, all tests pass.
用户创建
user_spec.rb (无工厂)
describe User do
before do
@user = User.new(name: "Example User", email: "user@example.com",
password: "foobar", password_confirmation: "foobar",
username: "username")
end
该应用程序的其他大多数测试都使用工厂.因此，决定将上述内容替换为致电工厂.
Most of the other tests for the app use factories. So, decided to replace the above with call to factory.
user_spec.rb (带有工厂)
describe User do
before do
@user = FactoryGirl.create(:user)
end
工厂
FACTORY
工厂看起来像这样.
factories.rb
FactoryGirl.define do
factory :user do
sequence(:name) { |n| "Person #{n}" }
sequence(:email) { |n| "person_#{n}@example.com" }
password "foobar"
password_confirmation "foobar"
sequence(:username) { |n| "username_#{n}" }
测试失败
TEST FAILURE
这是使用工厂创建用户时的测试失败.
Here is the test failure when using the factory to create the user.
user_spec.rb
Failures:
1) User when email address is already taken
Failure/Error: it { should_not be_valid }
expected valid? to return false, got true
# ./spec/models/user_spec.rb:101:in `block (3 levels) in <top (required)>'
Finished in 12.61 seconds
178 examples, 1 failure, 2 pending
测试
TEST
这是测试的一部分，当切换到出厂时会失败.
Here is the part of the test that fails when switching to the factory.
describe "when email address is already taken" do
before do
user_with_same_email = @user.dup
user_with_same_email.email = @user.email.upcase
user_with_same_email.save
end
it { should_not be_valid }
end
检查用户和USER.DUP
INSPECTION OF USER AND USER.DUP
我的第一个想法可能是在工厂创建的用户上使用.dup引起了问题.这是@user和@ user.dup在上述测试中使用时的输出(将puts @user.inspect和puts user_with_same_email.inspect行添加到describe块中.这两个puts都在user_with_same_email.save之后)
My first thought was perhaps using the .dup on the factory created user was causing problems. Here is the @user and the @user.dup when output from their use in the test above (by adding the lines puts @user.inspect and puts user_with_same_email.inspect into the describe block. Both of these puts are after the user_with_same_email.save).
完全没有(测试通过)
@用户
#<User id: nil, name: "Example User", email: "user@example.com",
created_at: nil, updated_at: nil,
password_digest: "$2a$04$I/71i.fpTwfp4PqRwAvU4eUEjEkW/wubx6uVBqfNBShq...",
remember_token: nil, admin: false, username: "username">
user_with_same_email
#<User id: 1178, name: "Example User", email: "USER@EXAMPLE.COM",
created_at: "2012-04-24 06:01:07", updated_at: "2012-04-24 06:01:07",
password_digest: "$2a$04$I/71i.fpTwfp4PqRwAvU4eUEjEkW/wubx6uVBqfNBShq...",
remember_token: "rMS9jM0d4lobLc-A-pTTqA", admin: false, username: "username">
工厂(测试失败)
@用户
#<User id: 739, name: "Person 67", email: "person_67@example.com",
created_at: "2012-04-24 05:54:28", updated_at: "2012-04-24 05:54:28",
password_digest: "$2a$04$n4tToBVM2elz92cfHPKvte6dfHSBj4jDxG.w6DyKtGUR...",
remember_token: "fy2iifmhXVTFa1__d1dBJg", admin: false, username: "username_67">
user_with_same_email
#<User name: "Person 67", email: "PERSON_67@EXAMPLE.COM",
created_at: nil, updated_at: nil,
password_digest: "$2a$04$n4tToBVM2elz92cfHPKvte6dfHSBj4jDxG.w6DyKtGUR...",
remember_token: "fy2iifmhXVTFa1__d1dBJg", admin: false, username: "username_67">
上面突出的是，@ user在不使用工厂的情况下尚未被保存，而在使用工厂时@user被保存.在这种情况下，我只是看不到它如何影响测试.
What stands out above is that @user is not already saved without using the factory, whereas when using the factory @user is saved. I'm just not seeing how this effects the test in this case.
任何帮助将不胜感激.谢谢！
Any help would be appreciated. Thanks!

推荐答案
工厂将记录放入数据库中.除非保存，否则User.new不会.原始测试不会检查是否创建了user_with_same_email，而是因为电子邮件存在而无法创建"it"(主题{@user}).对@user进行更改后，我不得不重写测试:
The factory puts the record in the DB. User.new doesn't until it is saved. The original test doesn't check if user_with_same_email gets created, rather that 'it' (subject { @user }) can't be created because the email exists. After making your change to the @user, I had to rewrite the test:
describe "when email address is already taken" do
let (:user_with_same_email) { @user.dup }
specify { user_with_same_email.should_not be_valid }
end
