Show HN: JavaScript unit testing in under 30 lines

This is quite interesting. Would be nice to have error exit code as well, which is important for a CI workflow.

That's a good idea. It'd be as simple as adding the following before line 19:

  process.on('exit', () => (process.exitCode = 1));

I didn't want to assume that people are executing the code in-browser or terminal for the purpose of this Gist, but feel free to fork for your needs.
