#RSpec

####StaticPagesコントローラーのテスト

spec/requests/static_pages.rb

require 'rails_helper'

RSpec.describe "StaticPages", type: :request do

  let(:base_title) { "Ruby on Rails Tutorial Sample App" }

  describe "GET /home" do
    it "returns http success" do
      get "/home"
      expect(response).to have_http_status(:success)
      assert_select "title", "#{base_title}"
    end
  end

  describe "GET /help" do
    it "returns http success" do
      get "/help"
      expect(response).to have_http_status(:success)
      assert_select "title", "Help | #{base_title}"
    end
  end

  describe "GET /about" do
    it "returns http success" do
      get "/about"
      expect(response).to have_http_status(:success)
      assert_select "title", "About | #{base_title}"
    end
  end

end

/homeで基本タイトルのみを表示するよう変更。
