Rails 3.1，rspec，后卫和spork在Windows上真的很慢
我想成为一个更好的测试人员。 设置有这么多问题我不知道它是否值得。
有人可以帮忙吗？
我在Windows机器上运行Rails 3.1，rspec，后卫水豚和spork。 我使用了防护sporkgem。 这是我运行bundle exec guard时得到的
看看“在421.87秒完成”这一行。 这是一次测试！
我看到我收到一个错误，警告spork抱怨没有fork支持（Windows问题），但后来这行“./magazine_slave.rb：22：在’run’”，应该表明magazine_slave运行（Windows运行spork与杂志而不是叉子）。
有任何想法吗？

这就是为什么spork是一个很好的工具。 它加载了rails环境，guard可以在不重新加载rails环境的情况下查找更改。 但是守卫sporkgem中有一个bug。 它不适用于Windows，因为它依赖于fork。 即使是坚硬的spork也不要在窗户上使用叉子 – spork。 非UNIX系统不支持Fork。
我研究了这个问题并最终得到了一个不同的方法。 我将逻辑删除到lib文件夹，并且不在规范中包含spec_helper文件。 然后rails不会加载，只有特定的测试逻辑。 这很快，迫使我编写更易读的代码。
