Question

RSpec でモデルをテストしたいのですが、見つけられないタイプミスに遭遇した可能性があります。誰かが私を少し助けてくれませんか？私は長い間それに苦労してきましたが、間違いを見つけることができません。前もって感謝します！

user_spec.rb

require 'spec_helper'

describe User do
     it "has a valid factory" do
        FactoryGirl.build(:user).should be_valid
     end
     it "is invalid without an e-mail"
     it "is invalid without a correct e-mail" 
     it "is invalid without a password" 
     it "is invalid without a matching password confrimation" 
end

user.rb

FactoryGirl.define do
    factory :user do |f|
        f.email "aabb@hh.de"
        f.password "ruby"
        f.password_confrimation "ruby"
    end
end

spec_helper.rb

# This file is copied to spec/ when you run 'rails generate rspec:install'
ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'rspec/autorun'
require 'factory_girl'

# Requires supporting ruby files with custom matchers and macros, etc,
# in spec/support/ and its subdirectories.
Dir[Rails.root.join("spec/support/**/*.rb")].each { |f| require f }

RSpec.configure do |config|
  # ## Mock Framework
  #
  # If you prefer to use mocha, flexmock or RR, uncomment the appropriate line:
  #
  # config.mock_with :mocha
  # config.mock_with :flexmock
  # config.mock_with :rr

  # Remove this line if you're not using ActiveRecord or ActiveRecord fixtures
  config.fixture_path = "#{::Rails.root}/spec/fixtures"

  # If you're not using ActiveRecord, or you'd prefer not to run each of your
  # examples within a transaction, remove the following line or assign false
  # instead of true.
  config.use_transactional_fixtures = true

  # If true, the base class of anonymous controllers will be inferred
  # automatically. This will be the default behavior in future versions of
  # rspec-rails.
  config.infer_base_class_for_anonymous_controllers = false

  # Run specs in random order to surface order dependencies. If you find an
  # order dependency and want to debug it, you can fix the order by providing
  # the seed, which is printed after each run.
  #     --seed 1234
  config.order = "random"
end
