I think there were a few CLs on the Gerrit but nothing being actively worked

• how do people feel about the existing test suite that comes along with nix source code or Lix?

1. gtest (offer only available in libexpr and libutil)

2. bash script

3. virtual machine

I am not usually a big python fan, but in that project we heard from some in the Rust community that they actually use Python to test CLI and seem to have success there.

In reply to @qyriad:katesiria.org
Python's fine, and it's already part of the buildsystem in other ways. If there's something that's a better idea or more preferred for another reason we can talk about that too
