"DejaGnu is a framework for [testing] other programs ... written in [Expect] ..."
[http://www.gnu.org/software/dejagnu/dejagnu.html]
It's also an official [GNU] project of the [FSF].

Unfortunately, DejaGnu's documentation online is not the full version.
My suggestion is to install DejaGnu, and read the new one with the install-packet.
If this item does not appear, install src-packet.
It will be located under file:///usr/share/dejagnu/html/book1.html.

In some ways [[enumerate]], [tcltest] is an alternative to DejaGnu.

https://github.com/oaken-source/asparagus%|%asparagus%|%: middleware for writing human-readable command line tests.  An example for a complete test would be:

  Given an executable "ls"
    When I run with parameters "-a"
    Then I should see ".."
    And it should return 0
