1. テストを書く

spec/models/contact_spec.rb

 it "has a valid factory" do
    expect(FactoryGirl.build(:contact)).to be_valid
  end

1. Run > Run > spec

1. Toggle auto-test

2. コードを書く

spec/factories/contacts.rb

FactoryGirl.define do
  factory :contact do
    firstname "Tatsuro"
    lastname "Ueda"
    sequence(:email) { |n| "weed#{n}@yahoo.co.jp"}
  end
end

1. 自動的にテストが走り、合格する

2. テストをFactoryGirl仕様に修正する

spec/models/contacts_spec.rb

  it "is valid with a firstname and lastname" do
    contact = FactoryGirl.build(
        firstname: 'Tatsuro',
        lastname: 'Tatsuro',
        email: '[e-mail]'
    )
    expect(contact).to be_valid
  end

  it "is invalid without a firstname" do
    #expect(Contact.new(firstname: nil)).to have(1).errors_on(:firstname)
    contact = FactoryGirl.build(:contact, firstname: nil)
    expect(contact).to have(1).errors_on(:firstname)
  end

  it "is invalid without a lastname" do
    #expect(Contact.new(lastname: nil)).to have(1).errors_on(:lastname)
    contact = FactoryGirl.build(:contact, lastname: nil)
    expect(contact).to have(1).errors_on(:lastname)
  end

  it "is invalid with a duplicate email address" do
    FactoryGirl.create(:contact, email: '[e-mail]')
    contact = FactoryGirl.build(:contact, email: '[e-mail]')
    expect(contact).to have(1).errors_on(:email)
  end

  describe "#name" do
    it "returns a contact's full name as a string" do
      contact = FactoryGirl.build(:contact,
          firstname: "Tatsuro", lastname: "Ueda"
      )
      expect(contact.name).to eq 'Tatsuro Ueda'
    end
  end

2. 「FactoryGirl」を省略可能にする

spec/spec_helper.rb

  config.include FactoryGirl::Syntax::Methods

1. テストを修正する

2. テストをFactoryGirl仕様に修正する

spec/models/contacts_spec.rb

  it "has a valid factory" do
    expect(build(:contact)).to be_valid
  end

  it "is valid with a firstname and lastname" do
    contact = build(:contact,
                    firstname: 'Tatsuro',
                    lastname: 'Tatsuro',
                    email: '[e-mail]'
    )
    expect(contact).to be_valid
  end

  it "is invalid without a firstname" do

  end

  it "is invalid without a lastname" do
    contact = build(:contact, lastname: nil)

  it "is invalid with a duplicate email address" do
    create(:contact, email: '[e-mail]')
    contact = build(:contact, email: '[e-mail]')
    expect(contact).to have(1).errors_on(:email)
  end

  describe "#name" do
    it "returns a contact's full name as a string" do
      contact = build(:contact,
                      firstname: "Tatsuro", lastname: "Ueda"
