;;; test-modeline-config-flycheck-segment.el --- Flycheck segment in modeline -*- lexical-binding: t; -*-

;;; Commentary:
;; Smoke test that the custom modeline's `mode-line-format' includes
;; a guarded reference to `flycheck-mode-line-status-text', and that
;; the guard requires both `mode-line-window-selected-p' and
;; `bound-and-true-p flycheck-mode'.  See
;; docs/design/flycheck-modeline-customization.org for the design.

;;; Code:
