测试命令行工具的最佳方法? [英] Best way to test command line tools?

问题描述

我们有大量自己编写并经常使用的命令行实用程序.目前，测试它们非常麻烦，因此，我们没有尽可能多地进行测试.

We have a large collection of command-line utilities that we write ourselves and use frequently. At the moment, testing them is very cumbersome and consequently, we don't do as much testing as we aught to.

我想知道是否有人可以推荐好的技术或工具来做好这种事情.

I am wondering if anyone can suggest good techniques or tools for doing a good job of this kind of thing.

这是 UNIX.

推荐答案

Aruba 是一个 Cucumber 扩展，用于测试用任何编程语言编写的命令行应用程序.

Aruba is a Cucumber extension for testing command line applications written in any programming language.

要使用它，您将需要 ruby​​ 来运行测试，但 aruba 的目的是提供一个预定义步骤定义的库，这样您就不需要编写任何 ruby​​ 代码来制作一个可行的测试套件.(尽管在某些时候您可能需要编写一些 ruby​​ 来制作一些自定义步骤.)

To use it, you will need ruby to run the tests, but the purpose of aruba is to provide a library of pre-defined step definitions so that you won't need to write any ruby code to make a workable test suite. (Though at some point you probably will want to write a bit of ruby to make a few custom steps.)
