Rspec 测试加载错误：无法加载此类文件 -- spec_helper (LoadError)

Question

我正在关注 RSpec 测试的一章，但我不断收到load error.

它告诉我首先创建一个新分支，然后创建两个新目录：Models和Spec. 在这些目录中，我应该制作两个文件；models/entry.rb和spec/entry_spec.rb。在 中spec/entry_spec.rb，我应该输入以下代码：

require_relative '../models/entry'


RSpec.describe Entry do

end

然后在我的models/entry.rb我应该把这个代码：

class Entry

end

然后我应该运行这个终端命令：

$ rspec spec/entry_spec.rb

并得到这个结果：

No examples found.

Finished in 0.00015 seconds (files took 0.1186 seconds to load)
0 examples, 0 failures

但是我总是收到这个加载错误，我不知道这是什么意思

如果有人愿意花时间帮助我解决我可能做错的事情，我将不胜感激。对不起，冗长的问题！

Answer 1

rspec spec/entry_spec.rb仔细检查您是否从应用程序目录的根目录运行，而不是从spec目录内运行。

Rspecspec自动添加到加载路径。如果您已经在spec目录中，rspec则将添加spec/spec到加载路径。
