Question

我的ruby RSpec Code失败了。我希望你能帮助我。当我添加电子邮件重复验证时，失败即将到来。

这是我的user_spec代码

require 'spec_helper'

describe User do

  before do
    @user = User.new(name: "Example User", email: "user@example.com")
  end

  subject {  @user }

  it { should respond_to(:name) }
  it { should respond_to(:email) }

  it { should be_valid }

  describe "when name is not present" do
    before { @user.name = " " }
    it { should_not be_valid }
  end

  describe "when email is not present" do
    before { @user.email = " " }
    it { should_not be_valid }
  end

  describe "when name is too long" do
    before { @user.name = "a" * 51 }
    it { should_not be_valid }
  end

  describe "when email format is invalid" do
    it "should be invalid" do
        addresses = %w[user@foo,com user_at_foo.org example.user@foo.foo@bar_baz.com foo@bar+baz.com]
        addresses.each do |invalid_address|
            @user.email = invalid_address
            @user.should_not be_valid
        end
    end
  end

  describe "when email format is valid" do
    it "should be valid" do
        addresses = %w[user@foo.COM A_US-ER@f.b.org frst.lst@foo.jp a+b@baz.cn]
        addresses.each do |valid_address|
            @user.email = valid_address
            @user.should be_valid
        end
    end
  end
  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
end

这是user.rb代码，它是模型

class User < ActiveRecord::Base
     validates :name, presence: true, length: { maximum: 50 }
     VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
     validates :email, presence: true, format: { with: VALID_EMAIL_REGEX }, uniqueness: { case_sensitive: false }
end

我在测试时失败了。我不知道什么是错的，我也没有在网上找到解决方案。

$ bundle exec rspec spec/models/user_spec.rb
Your Gemfile lists the gem rspec-rails (>= 0) more than once.
You should probably keep only one of them.
While it's not a problem now, it could cause errors if you change the version of just one of them later.
..[deprecated] I18n.enforce_available_locales will default to true in the future. If you really want to skip validation of your locale you can set I18n.enforce_available_locales = false to avoid this message.
F......

Failures:

     Failure/Error: it { should be_valid }
       expected valid? to return true, got false

Answer 1

我尝试了你的代码，但一切都变成了绿色。

我的猜测是你在早期的rspec运行中遇到了一些异常，因此你的测试数据库中有一些数据从未被成功删除过。

尝试

rake db:test:prepare

看看你是否还有问题。

这更多是通过进一步的故障排除建议而非实际答案。

接下来要查找的关键信息是哪个验证失败。在IRB控制台会话中尝试运行

user = User.new(name: "Example User", email: "user@example.com")
user.valid? # we're expecting this to return false
user.errors.messages # returns the message for the validation that's failing.

如果您知道哪些验证失败，那么缩小问题的范围就会轻松得多。
