我正在努力成为一个更好的测试员。设置有这么多问题，我想知道它是否值得。
有人可以帮忙吗？
我正在 Windows 盒子上运行 Rails 3.1、rspec、guard capybara 和 spork。我使用了 guard pig 肉 gem 。这是我运行 bundle exec guard 时得到的
查看“在 421.87 秒内完成”这一行。那是一项测试!
我看到我收到了一个错误，guard-spork 提示没有 fork 支持(Windows 问题)，但稍后这一行“./magazine_slave.rb:22:in `run'”应该表明 magazine_slave 运行(Windows 运行 spork with magazine而不是 fork )。
有任何想法吗？

最佳答案
因为 rspec 加载了 rails 环境，所以很慢。你拥有的 gem 越多，它变得越慢
这就是为什么 spork 是一个很好的工具。它加载 rails 环境，guard 可以在不重新加载 rails 环境的情况下查找更改。但是guard-spork gem中有一个错误。它不适用于 Windows，因为它依赖于 fork。即使是坚硬的 spork 也不要在 windows 上使用 fork - spork 可以。非 UNIX 系统不支持 Fork。
我研究了这个问题并最终采用了不同的方法。我制定了 lib 文件夹的逻辑，并且不在规范中包含 spec_helper 文件。然后 Rails 不会被加载，只有特定的测试逻辑。这很快，迫使我编写更具可读性的代码。
