Question

我正在关注RSpec测试的一章，但我不断得到load error。

它首先告诉我创建一个新分支，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spec/entry_spec.rb中，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我应该把这段代码：

class Entry

end

然后我应该运行这个终端命令：

$ rspec spec/entry_spec.rb

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

但我总是得到这个加载错误，我不知道这是什么意思

如果有人花时间帮我解决我可能做错的事情，我会非常感激。对不起，这个冗长的问题！

Answer 1

仔细检查您是否从app目录的根目录运行rspec spec/entry_spec.rb，而不是从spec目录中运行。

Rspec自动将spec添加到加载路径。如果您已经在spec目录中，则rspec会将spec/spec添加到加载路径中。

Answer 2

首先确保您已正确安装了rspec-rails：

rails g rspec:install

您不需要在/app中要求您提供模型文件或任何其他文件。当您需要rails_helper时，它们会自动加载。

# spec/models/entry_spec.rb
require 'rails_helper'
RSpec.describe Entry do

end

RSpec可以为您生成此规范：

rails generate rspec:model entry

您还应该在config/application.rb：

中设置生成器

# ...
config.generators do |g|
  g.test_framework :rspec
end

这样当您运行常规轨道生成器RSpec（例如rails g model entry）时，它也会为您创建规范文件。

请注意，旧版本的rspec-rails会require 'spec_helper'，而在当前版本中，您会使用require 'rails_helper'，因为它会将常规RSpec配置和rails设置分成两个单独的文件。

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