Module testing

Utilities for writing unit tests

This module contains utilities (types, helper functions and a Rust macro) that make it easier to write unit tests for Texlang primitives. It’s based on the philosophy that high-equality extensive unit tests will be written if and only if writing them is easy.

In general the main tool used in this module is the test_suite Rust macro, which generates a suite of unit tests for a set of primitives.
