Ruby 给了我与其他人类似的四次失败

Question

我不断收到一些从其他人那里看到的错误。这是错误消息：

   1) Failure:
   StaticPagesControllerTest#test_should_get_about     [C:/Sites/sample_app/test/controllers/static_pages_controller_test.rb:19]:
   <About | Ruby on Rails Tutorial Sample App> expected but was
   <About | Ruby on Rails Tutorial Sample App.>.
   Expected 0 to be >= 1.


   2) Failure:
   StaticPagesControllerTest#test_should_get_contact [C:/Sites/sample_app/test/controllers/static_pages_controller_test.rb:25]:
   <Contact | Ruby on Rails Tutorial Sample App> expected but was
   <Contact | Ruby on Rails Tutorial Sample App.>.
   Expected 0 to be >= 1.


   3) Failure:
   StaticPagesControllerTest#test_should_get_help [C:/Sites/sample_app/test/controllers/static_pages_controller_test.rb:13]:
   <Help | Ruby on Rails Tutorial Sample App> expected but was
   <Help | Ruby on Rails Tutorial Sample App.>.
   Expected 0 to be >= 1.


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

这里也是测试文件的代码：

 require 'test_helper'

 class StaticPagesControllerTest < ActionController::TestCase
   test "should get home" do
      get :home
      assert_response :success
      assert_select "title", "Ruby on Rails Tutorial Sample App"
   end

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

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

   test "should get contact" do
      get :contact
      assert_response :success
      assert_select "title", "Contact | Ruby on Rails Tutorial Sample App"
   end
 end

如何在我的应用程序中解决此问题？我是否必须为程序编写另一部分代码？

Answer 1

您应该尝试在测试中在Sample App 之后添加.（句点/句号），或者从您的视图中删除.。

像这样：

test "should get home" do
  get :home
  assert_response :success
  assert_select "title", "Ruby on Rails Tutorial Sample App."
end

消息Expected 0 to be >= 1 仅表示测试正在计算它可以在页面上找到内容（没有.）的次数，它计数为 0，但它预计计数至少为 1，因为这就是你在你的测试中断言。
