Question

按照Michael Hartl的Rails教程，我正在使用Rails中的Minitest测试我的静态页面的static_pages_controller_test.rb。

以下是require 'test_helper' class StaticPagesControllerTest < ActionController::TestCase test "should get home" do get :home assert_response :success assert_select "title", "Home | Microblog" end test "should get help" do get :help assert_response :success assert_select "title", "Help | Microblog" end test "should get about" do get :about assert_response :success assert_select "title", "About | Microblog" end end文件：

home.html.erb

这是主页<!DOCTYPE html> <html> <head> <title>Home | Microblog</title> </head> <body> <h1>Microblog</h1> <p> This is the homepage for Microblog, a brand new microblogging app. </p> </body> </html>文件：

help.html.erb

about.html.erb和rake基本上包含相同的内容，但略有不同。

因此，根据我的理解，测试应该通过。

然而，当我运行Run options: --seed 47355 # Running: FFF Finished in 0.112314s, 26.7109 runs/s, 53.4217 assertions/s. 1) Failure: StaticPagesControllerTest#test_should_get_home [/Users/TXC/code/microblog/test/controllers/static_pages_controller_test.rb:7]: <Home | Microblog> expected but was <Home | Microblog>.. Expected 0 to be >= 1. 2) Failure: StaticPagesControllerTest#test_should_get_help [/Users/TXC/code/microblog/test/controllers/static_pages_controller_test.rb:13]: <Help | Microblog> expected but was <Help | Microblog>..

Expected 0 to be >= 1. 3 runs, 6 assertions, 3 failures, 0 errors, 0 skips时，我得到：

<Home | Microblog> expected but was
    <Home | Microblog>..

特别是，我不明白为什么会这样：

我错过了什么？

更新：我继续学习本教程并遵循高级测试设置部分中的指南。

以下是我使用Guard运行所有测试时得到的结果：

{{1}}

我一直在调查问题的原因，但到目前为止还没有找到任何结论。

有什么想法吗？

Answer 1

我不理解您对竖线字符的评论，而不是介于＆lt;％=％＆gt;之间。因为：您的文件没有测试＆＃39;＆＃39;产生＆＃39;与erb的标题。这将在本教程后面发生。在这个测试中，你应该测试简单的＆＃39; HTML格式。这有什么问题吗？

我不记得这个测试到底是什么，但是它可能与你的路由有关吗？

Answer 2

所以，我一直关注本教程，在下一章（第4章）中，我们在某个时候创建了full_title帮助器并删除了＆lt;％provide（：title，＆＃34; Home＆＃34;）％＆gt;从意见。

我不确定如何，但这解决了问题并使测试通过：

希望如果你遇到同样的问题会有所帮助。
