;;; test-linear-config.el --- Tests for linear-config.el -*- lexical-binding: t; -*-

;;; Commentary:
;; Covers the lazy API-key loader and the keybinding wiring.  pearl
;; itself is never loaded here (it's a deferred :load-path package), so
;; `pearl-api-key' is declared special below to make the dynamic
;; let-bindings reach `cj/linear--ensure-api-key'.  `cj/auth-source-secret-value'
;; is stubbed — no authinfo.gpg / GPG access in the tests.

;;; Code:

(require 'ert)
(require 'cl-lib)
(require 'linear-config)

;; linear-config declares this with a bare (defvar pearl-api-key), which
;; is only file-local; declare it special here so the let-bindings are dynamic.
