Rails Tutorial Authenticate Issue - ruby-on-rails

Question

I'm following the Rails Tutorial Modeling Users Chapter: http://www.railstutorial.org/book/modeling_users#cha-modeling_users.
My user.rb looks like:
class User < ActiveRecord::Base
before_save { self.email = email.downcase }
has_secure_password
validates :name, presence: true, length: { maximum: 50 }
VALID_EMAIL_REGEX = /\A[\w+\-.]+#[a-z\d\-]+(?:\.[a-z\d\-]+)*\.[a-z]+\z/i
validates :email, presence: true,
format: { with: VALID_EMAIL_REGEX },
uniqueness: { case_sensitive: false }
validates :password, length: { minimum: 6 }
end
and my user model spec looks like:
describe User, :type => :model do
before do
#user = User.new(name: "Example User", email: "user#example.com",
password: "foobar", password_confirmation: "foobar")
end
subject { #user }
it { should respond_to(:name) }
it { should respond_to(:email) }
it { should respond_to(:password_digest) }
it { should respond_to(:password) }
it { should respond_to(:password_confirmation) }
it { should respond_to(:authenticate) }
it { should be_valid }
... (other methods are here)
describe "when password is not present" do
before do
#user = User.new(name: "Example User", email: "user#example.com",
password: "foobar", password_confirmation: "foobar")
end
it { should_not be_valid }
end
describe "return value of authenticate method" do
before { #user.save }
let(:found_user) { User.find_by(email: #user.email) }
describe "with valid password" do
it { should eq found_user.authenticate(#user.password) }
end
describe "with invalid password" do
let(:user_for_invalid_password) { found_user.authenticate("invalid") }
it { should_not eq user_for_invalid_password }
specify { expect(user_for_invalid_password).to be_false }
end
end
Which I'm pretty sure is exactly a duplication what the Rails Tutorial code is, but I'm getting the following failed test errors:
rspec ./spec/models/user_spec.rb:83 # User when password is not present should not be valid
rspec ./spec/models/user_spec.rb:108 # User return value of authenticate method with invalid password should be false

I checked this out by looking at the Ruby on Rails Tutorial Book's source code (Rails 4) at GitHub: spec/models/user_spec.rb. Based on the code there, it looks like your passwords are currently of acceptable type and that's why your test is failing. I mean your passwords are good. foobar is a valid password. Below an empty string is passed to the User model validation.
describe "when password is not present" do
before do
#user = User.new(name: "Example User", email: "user#example.com",
password: " ", password_confirmation: " ")
end
it { should_not be_valid }
end
The second one I'm not sure, but would it help if you tried the Rails 3 spec/models/user_spec.rbrelated code for the same test:
describe "with invalid password" do
let(:user_for_invalid_password) { found_user.authenticate("invalid") }
it { should_not == user_for_invalid_password }
specify { user_for_invalid_password.should be_false }
end
It looks slightly different but it's testing the same thing. This is just suggestion, because I'm not sure what's going wrong.

It looks like a couple of methods are missing (if you're trying to match the tutorial exactly) Listing 6.25 & 6.28:
describe "when password doesn't match confirmation" do
before { #user.password_confirmation = "mismatch" }
it { should_not be_valid }
end
describe "with a password that's too short" do
before { #user.password = #user.password_confirmation = "a" * 5 }
it { should be_invalid }
end
