我不知道是什么问题。我看看它说，但我甚至C＆P从教程中的代码，仔细检查我做了什么，以确保一切都正确输入。

该故障并没有出现，直到我添加的电子邮件验证。

Answer 1

请确保您正在创建@user你开始测试之前..你在你的用户测试这些行？ （rails tutorial listing 6.16）

before do
    @user = User.new(name: "Example User", email: "[email protected]")
end

Answer 2

该错误是很清楚！你设置电子邮件至零级。这意味着你应该到电子邮件设置，这是我们说一个用户

 @user.email = "something"

该错误是抱怨没有用户，并且不会有任何电子邮件用户。

为了让在这里工作是一个示例代码，这将帮助你解决这个问题。

 describe "validations" do
   before(:each) do
     @user = User.new(name: "gates", email: "[email protected]")
   end
   it "should be invalid" do
     invalid_emails = %w{gs@gmail p.com name.gmail.com foo.ymail}
     invalid_emails.each do |invalid_email|
       @user.email = invalid_email
       expect(@user.email).to_not be_valid
    end
   end

   it "should be valid" do
    @user.name = "somename"
    valid_emails = %w{[email protected] [email protected] [email protected] 
    [email protected]}
    valid_emails.each do |valid_email|
     @user.email = valid_email
     expect(@user.email).to be_valid
    end
   end  
 end

请确保你已经创建了用户的固定在夹具文件夹中。

希望这可以帮助！
