Model Test

• Enter the following command:

rails generate model Sponsor name:string phone:string description:text contact_email:string contact_url:string current:boolean 

• Enter the command "rails db:migrate".
• Edit the file test/models/sponsor_test.rb. Replace everything between the lines "class SponsorTest < ActiveSupport::TestCase" and the final "end" command with the following:

  def setup
    @sponsor = Sponsor.new(name: 'Valere Consulting and Recruiting',
                           phone: '612-555-0100',
                           description: 'Exceptional talent',
                           contact_email: '[email protected]',
                           contact_url: 'http://valere.com/',
                           current: true)
  end

  test 'should be valid' do
    assert @sponsor.valid?
  end

  test 'name must be present' do
    @sponsor.name = nil
    assert_not @sponsor.valid?
  end

  test 'name should be no more than 255 characters long' do
    @sponsor.name = 'a' * 256
    assert_not @sponsor.valid?
    @sponsor.name = 'a' * 255
    assert @sponsor.valid?
  end

  test 'phone number should be no more than 255 characters long' do
    @sponsor.phone = '5' * 256
    assert_not @sponsor.valid?
    @sponsor.phone = '5' * 255
    assert @sponsor.valid?
  end

  test 'description should be no more than 4095 characters long' do
    @sponsor.description = 'a' * 4096
    assert_not @sponsor.valid?
    @sponsor.description = 'a' * 4095
    assert @sponsor.valid?
  end

  test 'contact_email should be no more than 255 characters long' do
    @sponsor.contact_email = 'a' * 244 + '@example.com'
    assert_not @sponsor.valid?
    @sponsor.contact_email = 'a' * 243 + '@example.com'
    assert @sponsor.valid?
  end

  test 'contact_url should be no more than 255 characters long' do
    @sponsor.contact_url = 'http://www' + 'a' * 242 + '.com'
    assert_not @sponsor.valid?
    @sponsor.contact_url = 'http://www' + 'a' * 241 + '.com'
    assert @sponsor.valid?
  end

• Enter the command "sh testm.sh". The last 6 new model tests fail.
• Edit the app/models/sponsor.rb file. Add the line "#" just before the line "class Sponsor < ApplicationRecord".
• Edit the app/models/sponsor.rb file. Insert the following code between the line "class Sponsor < ApplicationRecord" and "end":

  validates :name, presence: true, length: { maximum: 255 }
  validates :phone, length: { maximum: 255 }
  validates :description, length: { maximum: 4095 }
  validates :contact_email, length: { maximum: 255 }
  validates :contact_url, length: { maximum: 255 }

• Enter the command "sh testm.sh". All tests should pass.
• Enter the command "sh git_check.sh". All tests should pass, and there should be no offenses.
