;;; test-ai-vterm--tmux-session-name.el --- Tests for cj/--ai-vterm-tmux-session-name -*- lexical-binding: t; -*-

;;; Commentary:
;; The tmux session name is derived from the project's basename so that
;; reopening Claude on the same project (e.g. after an Emacs crash)
;; reattaches to the same tmux session rather than spawning a new one.
;; Whitespace in the basename gets converted to hyphens so the name is
;; safe to pass on a tmux command line.

;;; Code:

(require 'ert)

(require 'ai-vterm)
