如果可能的话，我会将两个项目中的公共功能提取到一个gem中，然后进行测试。

If possible I'd extract the common functionality out of the two projects into a gem and test it once there.

由于某些原因，两个项目真的必须单独实现相同的功能：

If for some reason the two projects really have to separately implement the same functionality:

您可以通过将一个gem中的步骤定义放在一个文件中，并指示用户 require 该文件在他们的env.rb。

You can provide step definitions in a gem simply by putting them in a file and instructing the user to require that file in their env.rb.

我不知道一种方法提供功能在gem，可以简单地运行到位，因此您必须提供一个生成器将功能复制到features目录。如果你要生成的功能，它可能更简单的用户生成步骤定义太。

I don't know of a way to provide features in a gem that can simply be run in place, so you'll have to provide a generator that copies the features to the features directory. And if you're going to generate the features it's probably simpler for the user to generate the step definitions too.
