;;; test-video-audio-recording--start-race.el --- start-race fix tests -*- lexical-binding: t; -*-

;;; Commentary:
;; Tests for the wf-recorder start-race fix: the poll that waits for a dying
;; wf-recorder to release the compositor capture before launching a new one, and
;; the fail-fast timing predicate that tells a 0.5s failed start from a real
;; recording.  The pgrep wrapper and the live start/stop wiring are exercised in
;; the daemon, not here; the poll is tested with an injected predicate so no real
;; process is needed.

;;; Code:

(require 'ert)

;; Stub dependencies before loading the module.
(defvar cj/custom-keymap (make-sparse-keymap)
