;;; test-prog-webdev-setup.el --- Tests for cj/webdev-setup mode hook -*- lexical-binding: t; -*-
;;; Commentary:
;; Sibling tests cover the prettier format wrapper and command builder.
;; `cj/webdev-setup' (the shared per-buffer preferences for TS/JS/TSX
;; modes) was uncovered. Same stub-and-assert shape as the prog-python
;; setup test.
