;;; test-custom-ordering-wrappers.el --- Tests for the user-facing ordering wrappers -*- lexical-binding: t; -*-
;;; Commentary:
;; Sibling tests cover each `cj/--<op>' internal in isolation. This
;; file covers the buffer-mutating wrapper commands:
;;
;; cj/arrayify, cj/listify, cj/arrayify-json, cj/arrayify-python
;; cj/unarrayify
;; cj/toggle-quotes
;; cj/reverse-lines
;; cj/number-lines
;; cj/alphabetize-region
;; cj/comma-separated-text-to-lines
;;
;; Each test runs the wrapper inside `with-temp-buffer' with the whole
;; buffer as the region and asserts the contents after replacement.
