Cram is a test framework for command line programs, originally written for mercurial's test suite.
I like the approach - it just reads a shell transcript and runs the commands it finds. If the output doesn't match, it shows you a diff. It's kind of like doctest.
It looks refreshingly simple to get started with, something that so many other test frameworks fail horribly at.
A while ago, I wrote something similar for work. After trying and failing to find a testing framework that wasn't over-engineered, I wrote a script that looks in
./test/, and runs every file named
whatever.test, and compares output to files
whatever.test.stderr, if they exist.
If not, it just uses the return value to determine success.
I loved how easy it was to add a test. Just write a script! There is no step two.
