RoR 教程第 3 章 - Guard 检测更改但未完全执行测试

Question

我目前正在关注这本书和视频，在视频中，Hartl 运行是一个保护文件，因此它会在进行任何更改后自动运行进行测试。所以在视频中，当他在守卫模式下按下 return 时，它说：

17:35:31 - INFO - Running: test/controllers/static_pages_controller_test.rb

接着是

Started 

   2/2 [=======] 100% Time: 00:00:00, Time: 00:00:00

Finished in 0.214142s
2 tests, 2 assumptions, 0 failures, 0 errors, 0 skips
[1] guard(main)>

我假设测试已经实际执行。

但是当我对 /test/controllers/static_pages_controller_test.rb 进行更改时，守卫运行s 但它运行s 直到行 where is 说，就是这样：

INFO - Running: test/controllers/static_pages_controller_test.rb

我已经运行调试了守卫，这就是发生的事情：

chocoberry4@sample_app:~/workspace (static-pages) $ bundle exec guard -d

19:39:51 - INFO - Running: test/controllers/static_pages_controller_test.rb
19:39:51 - DEBUG - Command execution: tmux set -q status-left-bg red

然后我在这里对文件"test/controllers/static_pages_controller_test.rb"进行了更改...

19:39:51 - DEBUG - Start interactor
19:39:58 - DEBUG - Interactor was stopped or killed
19:39:58 - DEBUG - Hook :run_on_modifications_begin executed for Guard::Minitest
19:39:58 - INFO - Running: test/controllers/static_pages_controller_test.rb
19:39:58 - DEBUG - Command execution: tmux set -q status-left-bg red

19:39:58 - DEBUG - Start interactor

Answer 1

2 tests, 2 assumptions, 0 failures, 0 errors, 0 skips

表示守卫成功运行 2个包含两个假设（assertions）的测试。

调试日志中的消息告诉您缺少依赖项。您可以使用 Hartl 建议的免费 cloud 9 和 heroku 设置来避免让自己头疼，因为它会正常工作 'out of the box'。

否则你需要仔细检查并添加调试抱怨的缺少的 gems，ruby_gntp 和 libnotify。之后您可能会遇到其他错误，但这是您需要开始的地方。运行 bundle install 将它们添加到您的 gem 文件后。

编辑：（因为 OP 使用的是 Cloud9）

springgem 中存在一个错误，它会留下实例运行ning，直到您的所有 cloud9 RAM 都被消耗并且 Guard 由于内存不足而无法完成。如果是这种情况，您的选择是终止 spring 个实例或重新启动您的应用并重试。但是随着您的测试套件随着教程的增加而增长，杀死 PID 或重新启动将变得太频繁而不必理会。最好的解决方案是不要在内存有限的免费 cloud9 帐户上使用 guard。当教程建议时运行 bundle exec rake test。

如果仍有问题，请检查您的 gem 文件是否与教程中的文件完全匹配。
