Question

我学习了 Michael Hartl (https://www.railstutorial.org/) 的 Ruby on Rails 教程。

在 3.6.2 中，我想使用 Guard 自动测试。我写了和本书一样的代码并修改了测试文件，但是测试没有自动运行。

这是执行Guard的消息。

[vagrant@localhost sample_app]$ bundle exec guard

Done.

14:33:01 - INFO - Guard is now watching at '/vagrant/sample_app'

这是 Guardfile。

  end

end

这是 static_pages_spec.rb

require 'spec_helper'

describe "Static pages" do

  subject { page }

  shared_examples_for "all static pages" do
    it { should have_content(heading) }
    it { should have_title(full_title(page_title)) }
  end

  describe "Home page" do
    before { visit root_path }
    let(:heading)    { 'Sample App' }
    let(:page_title) { '' }

    it_should_behave_like "all static pages"
    it { should_not have_title('| Home') }
  end

  describe "Help page" do
    before { visit help_path }
    let(:heading) {'Help'}
    let(:page_title) {'Help'}

    it_should_behave_like "all static pages"
  end

  end
end

我自己解决了这个问题。

试试这个命令。

bundle exec guard -p
