Hartl Rspec测试失败

Question

I keep getting these these two errors during chapter 10 of Hartl's RoR guide and cannot seem to find the solution to them. I've been troubleshooting for awhile, but the answer continues to evade me. Is there something wrong with the USER.rb?

 FAIL["test_name_should_not_be_too_long", UserTest, 0.436818]
 test_name_should_not_be_too_long#UserTest (0.44s)
        Expected true to be nil or false
        test/models/user_test.rb:25:in `block in <class:UserTest>'

 FAIL["test_name_should_be_present", UserTest, 0.441668]
 test_name_should_be_present#UserTest (0.44s)
        Expected true to be nil or false
        test/models/user_test.rb:15:in `block in <class:UserTest>'

Here is my User_test

require 'test_helper'

class UserTest < ActiveSupport::TestCase

  def setup
    @user = User.new(name: "Example User", email: "user@example.com", password: "foobar", password_confirmation: "foobar")
  end

  test "should be valid" do
    assert @user.valid?
  end

  test "name should be present" do
    @user.name = ""
    assert_not @user.valid?
  end

test "email should be present" do
    @user.email = "     "
    assert_not @user.valid?
  end

test "name should not be too long" do
    @user.name = "a" * 51
    assert_not @user.valid?
  end

test "email should not be too long" do
    @user.email = "a" * 244 + "@example.com"
    assert_not @user.valid?
  end

test "email validation should accept valid addresses" do
    valid_addresses = %w[user@example.com USER@foo.COM A_US-ER@foo.bar.org
                         first.last@foo.jp alice+bob@baz.cn]
    valid_addresses.each do |valid_address|
      @user.email = valid_address
      assert @user.valid?, "#{valid_address.inspect} should be valid"
    end
  end

test "email validation should reject invalid addresses" do
    invalid_addresses = %w[user@example,com user_at_foo.org user.name@example.
                           foo@bar_baz.com foo@bar+baz.com]
    invalid_addresses.each do |invalid_address|
      @user.email = invalid_address
      assert_not @user.valid?, "#{invalid_address.inspect} should be invalid"
    end
  end

  test "email addresses should be unique" do
    duplicate_user = @user.dup
    duplicate_user.email = @user.email.upcase
    @user.save
    assert_not duplicate_user.valid?
  end

  test "email addresses should be saved as lower-case" do
    mixed_case_email = "Foo@ExAMPle.CoM"
    @user.email = mixed_case_email
    @user.save
    assert_equal mixed_case_email.downcase, @user.reload.email
  end


  test "password should have a minimum length" do
    @user.password = @user.password_confirmation = "a" * 5
    assert_not @user.valid?
  end

  test "authenticated? should return false for a user with nil digest" do
    assert_not @user.authenticated?(:remember, '')
  end

end

Answer 1

That is a good tutorial. I see you're missing validations in your user.rb

  validates :name,  presence: true, length: { maximum: 50 }

Add this line to the user.rb model specification and both errors should be resolved.
