Rails Tutorial10章の10.32のテストが通りません

みなさん、こんにちは。
現在Rails tutorial第３版、10章に取り組んでおります。
10.32のテストが通りません。

以下、テスト結果全文です。

xxxxxxxxxxxxxxxxxxxxxxxxxxx:sample_app xxxxxxxxx$ bundle exec rake test

また、エラーが出ているテストが以下です。

<test/integration/users_signup_test.rb>

require 'test_helper'

class UsersSignupTest < ActionDispatch::IntegrationTest

  def setup
    ActionMailer::Base.deliveries.clear
  end

  test "invalid signup information" do
    get signup_path
    assert_no_difference 'User.count' do
      post users_path, user: {name: "", email: "user@invalid", password: "foo", password_confirmation: "bar"}
    end
    assert_template 'users/new'
  end

  test "valid signup information with account activation" do
    get signup_path
    assert_difference 'User.count',1 do
      post users_path, user: { name: "Example User",
                          email: "user@example.com",
                          password:      "password",
                  password_confirmation: "password"}
    end
    # 配信されたメッセージが１つであるかどうかを確認する
    assert_equal 1, ActionMailer::Base.deliveries.size
    user = assigns(:user)
    assert_not user.activated?
    # 有効化していない状態でログインしてみる
    log_in_as(user)
    assert_not is_logged_in?
    # 有効化トークンが不正な場合
    get edit_account_activation_path("invalid token")
    assert_not is_logged_in?
    # トークンは正しいがメールアドレスが無効な場合
    get edit_account_activation_path(user.activation_token, email: 'wrong')
    # 有効化トークンが正しい場合
    get edit_account_activation_path(user.activation_token, email:user.email)
    assert user.reload.activated?
    follow_redirect!
    assert_template 'user/show'
    assert is_logged_in?
  end

end

エラーを見るに、「user/showしか求めてないのにいろいろレンダリングしてしまっているよ」ということが言われているのかな？と考えております。

なお、user/showが以下になります。

app/views/users/show.html.erb

<% provide(:title, @user.name) %>
<div class="row">
  <aside class="col-md-4">
    <section class="user_info">
      <h1>
        <%= gravatar_for @user %>
        <%= @user.name %>
      </h1>
    </section>
  </aside>
</div>

app/views/layouts/application.html.erb

<!DOCTYPE html>
<html>
<head>
  <title><%= full_title(yield(:title)) %></title>
  <%= stylesheet_link_tag    'application', media: 'all', 'data-turbolinks-track' => true %>
  <%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
  <%= csrf_meta_tags %>
  <%= render 'layouts/shim' %>
</head>

<body>
  <%= render 'layouts/header' %>
  <div class="container">
    <% flash.each do |message_type, message| %>
      <%= content_tag(:div, message, class: "alert alert-#{message_type}") %>
    <% end %>
    <%= yield %>
    <%= render 'layouts/footer' %>
    <%= debug(params) if Rails.env.development? %>
  </div>
</body>

</html>

どなたか、原因がおわかりの方がいらっしゃいましたら、ご教示頂きたく存じます。
よろしくお願いいたします。
