Aruba reference

What is Aruba?

Aruba is a testing framework that helps you test your command-line applications.

It can help you to:

• Test CLI apps written in any programming language.
• Manipulate the file system and process environment.
• Run your tests inside a sandbox that’s reset between each test.

By default, Aruba runs your commands in a separate child process.
