;;; test-prog-python--format-wiring.el --- Verify the Python formatter is wired -*- lexical-binding: t; -*-
;;; Commentary:
;; Three checks for the Python formatter:
;; 1. `blacken-buffer' is fboundp after the prog-python config loads.
;; 2. C-; f in `python-ts-mode-map' resolves to `blacken-buffer'.
;; 3. The `black' executable is on PATH (skipped if not installed).
;;; Code:
(require 'ert)
(add-to-list 'load-path (expand-file-name "modules" user-emacs-directory))
(add-to-list 'load-path (expand-file-name "tests" user-emacs-directory))
(require 'testutil-format-wiring)
(format-test--ensure-packages-init)
;; use-package's `:bind (:map ...)' defers until the named map exists.
;; Loading python.el populates `python-ts-mode-map'; loading blacken
;; resolves the binding form's late-binding hook.
