Question

我正在关注Michael Hartl的Ruby on Rails Tutorial。在 3.4.1测试标题（红色）部分中，作者使用assert_select viz编写了一个最小的测试。

test "should get home" do
  get static_pages_home_url
  assert_select "title", "Home | Ruby on Rails Tutorial Sample App"
end

然后他希望在运行rails测试时输出以下输出：

1 tests, 1 assertions, 1 failures, 0 errors, 0 skips

但是，当我在本地系统上运行完全相同的测试时，我会收到此失败消息：

# Running:

FF

Failure:
StaticPagesControllerTest#test_should_get_home [/Users/gurpreet/environment/sample_app/test/controllers/static_pages_controller_test.rb:7]:
<Home | Ruby on Rails Tutorial Sample App> expected but was
<SampleApp>..
Expected 0 to be >= 1.

有人请解释为什么我没有得到预期的测试结果。请注意，本教程中的实际部分有3个测试和6个断言，但我刚刚发布了相关的可读性详细信息，使用单个测试和单个断言。

这是完整的控制器测试类：

require 'test_helper'

class StaticPagesControllerTest < ActionDispatch::IntegrationTest
  test "should get home" do
    get static_pages_home_url
    assert_response :success
    assert_select "title", "Home | Ruby on Rails Tutorial Sample App"
  end

  test "should get help" do
    get static_pages_help_url
    assert_response :success
    assert_select "title", "Help | Ruby on Rails Tutorial Sample App"
  end

  test "should get about" do
    get static_pages_about_url
    assert_response :success
    assert_select "title", "About | Ruby on Rails Tutorial Sample App"
  end
end

正如我之前提到的，它包含类似性质的额外测试。我之前只发布了这个类的片段。

控制器的View部分故意省略<title>标记以使测试失败。例如，对于home.html.erb

<!DOCTYPE html>
<html>
  <head>
  </head>
  <body>
    <h1>Sample App</h1>
    <p>
      This is the home page for the
      <a href="http://www.railstutorial.org/">Ruby on Rails Tutorial</a>
      sample application
    </p>
  </body>
</html>

这可能是因为您使用的是Minitest内置的默认报告程序。我看到了带有minitest-reporters gem的类似Minitest摘要： https://github.com/kern/minitest-reporters

rails测试，获得失败：..预期0为＆gt; = 1
