;;; testutil-vterm-buffers.el --- Shared helpers for vterm/agent buffer tests -*- lexical-binding: t; -*-
;;; Commentary:
;; Cleanup helpers and a fake-vterm constructor used across the
;; ai-vterm and vterm-toggle test files. Before this module, each
;; test file re-implemented the same `(dolist (b (buffer-list))
;; (when (string-prefix-p ...) (kill-buffer b)))' loop with a
;; different prefix.
;;; Code:
(require 'cl-lib)
(defun cj/test--call-as-gui (fn)
"Call FN with `env-terminal-p' stubbed to return nil (a GUI frame).
The AI-vterm interactive commands refuse to run in a terminal frame
via `cj/--ai-vterm-refuse-in-terminal'. A batch test run is itself a
terminal frame, so tests that exercise the GUI-frame window behavior
of those commands call them through this helper to present a GUI
context."
(cl-letf (((symbol-function 'env-terminal-p) (lambda () nil)))
(funcall fn)))
(defun cj/test--kill-buffers-matching-prefix (prefix)
"Kill all live buffers whose name starts with PREFIX."
(dolist (b (buffer-list))
(when (string-prefix-p prefix (buffer-name b))
(kill-buffer b))))
(defun cj/test--kill-agent-buffers ()
"Kill all live buffers whose name matches the AI-vterm prefix \"agent [\"."
(cj/test--kill-buffers-matching-prefix "agent ["))
(defun cj/test--kill-test-vterm-buffers ()
"Kill all live buffers whose name starts with \"*test-vterm\"."
(cj/test--kill-buffers-matching-prefix "*test-vterm"))
(defun cj/test--make-fake-vterm-buffer (name)
"Return a buffer named NAME with `major-mode' set to `vterm-mode'.
Avoids actually launching a vterm process by setting the mode
buffer-locally. Used by tests that need a buffer satisfying the
vterm-mode predicate without the side-effects of `(vterm)'."
