在Hartl的Rails教程的第7章中没有使用rspec测试

Question

我在Michael Hartl的Rails教程的第7.1.3节中，我无法让FactoryGirl在测试中正常工作。它似乎不是FactoryGirl的问题，因为我也尝试在before hook中创建User with User.create并遇到同样的问题。以下是我得到的结果：

我在测试运行时在浏览器中截取了错误的屏幕截图:(无法找到在控制台中查看结果的方法。当我运行测试控制台时，它们没有显示。）

我已重新启动服务器和控制台。并且已经在测试环境中进行了迁移以确保其是最新的。

Answer 1

我刚刚过了7.1.3章，所以我为你查了一下。

在书中：

describe "Profile page" do
    let(:user) { FactoryGirl.create(:user) }
    before { visit user_path(user) }

    it { should have_content(user.name) }
    it { should have_title(user.name) }
end

您的代码：

describe "Profile page" do
    let(:user) { FactoryGirl.create(:user) }
    before { visit user_path(@user) }

    it { should have_content(@user.name) }
    it { should have_title(@user.name) }
end

尝试删除＆＃39; @＆＃39;在@user变量中，如果可行，请告诉我。

Michael Hartl的教程目前正在使用RSpec 2.13.1。 RSpec 3有许多重大变化，如下所述：https://relishapp.com/rspec/docs/upgrade

如果您正在学习，在完成他的教程时，我强烈建议您使用与他相同的宝石版本：

source 'https://rubygems.org'
ruby '2.0.0'
#ruby-gemset=railstutorial_rails_4_0

gem 'rails', '4.0.8'

group :development, :test do
  gem 'sqlite3', '1.3.8'
  gem 'rspec-rails', '2.13.1'
end

group :test do
  gem 'selenium-webdriver', '2.35.1'
  gem 'capybara', '2.1.0'
end

gem 'sass-rails', '4.0.1'
gem 'uglifier', '2.1.1'
gem 'coffee-rails', '4.0.1'
gem 'jquery-rails', '3.0.4'
gem 'turbolinks', '1.1.1'
gem 'jbuilder', '1.0.2'

group :doc do
  gem 'sdoc', '0.3.20', require: false
end

group :production do
  gem 'pg', '0.15.1'
  gem 'rails_12factor', '0.0.2'
end
