如何在Ruby模块中包含单元测试? [英] How to include unit tests in a ruby module?

问题描述

我试图在现在，我可以运行执行此源文件的单元测试.

Now, I can run the unit-tests executing this source file.

但是，当我需要/从另一个脚本加载它们时，它们也会运行.如何避免这种情况?

But, they are also run when I require/load them from another script. How can this be avoided ?

除非不鼓励这种做法，否则使用Ruby是否有更惯用的方式来实现这一目标?

Is there a more idiomatic way to achieve this with Ruby, unless this practice is discouraged ?

推荐答案

我个人从来没有听说过有人试图在Ruby中这样做.这绝对不是标准做法.也就是说，您也许可以利用此技巧:

Personally I've never heard of anyone trying to do this in Ruby. It's definitely not a standard practice. That said you may be able to leverage this trick:

if __FILE__ == $0
  # Do something.. run tests, call a method, etc. We're direct.
end

if块中的代码仅在直接执行文件时执行，而不是在其他库或应用程序需要时执行.

The code in the if block will only execute if the file is executed directly, not if it's required by another library or application.
