+;;; test-video-audio-recording--normalize-recording-dir.el --- Tests for recording-dir normalization -*- lexical-binding: t; -*-
+
+;;; Commentary:
+;; Unit tests for cj/recording--normalize-recording-dir.
+;; The recording target is always a directory that ffmpeg writes a
+;; timestamped file into.  Normalization must yield an absolute directory
+;; path with a trailing slash so the *selected* directory (not its parent)
+;; is the one created and recorded into.
+
+;;; Code:
+
+(require 'ert)
+
+;; Stub dependencies before loading the module
+(defvar cj/custom-keymap (make-sparse-keymap)
+  "Stub keymap for testing.")
+
+(require 'video-audio-recording)
+
+;;; Normal Cases
+
+(ert-deftest test-video-audio-recording--normalize-recording-dir-normal-adds-trailing-slash ()
+  "Normal: a path without a trailing slash becomes a directory path."
+  (should (equal "/tmp/foo/"
+                 (cj/recording--normalize-recording-dir "/tmp/foo"))))
+
+(ert-deftest test-video-audio-recording--normalize-recording-dir-normal-idempotent ()
+  "Normal: a path that is already a directory is returned unchanged."
+  (should (equal "/tmp/foo/"
+                 (cj/recording--normalize-recording-dir "/tmp/foo/"))))
+
+;;; Boundary Cases
+
+(ert-deftest test-video-audio-recording--normalize-recording-dir-boundary-spaces-preserved ()
+  "Boundary: spaces in the path are preserved (quoting happens at the shell)."
+  (should (equal "/tmp/my recordings/"
+                 (cj/recording--normalize-recording-dir "/tmp/my recordings"))))
+
+(ert-deftest test-video-audio-recording--normalize-recording-dir-boundary-relative-expands-absolute ()
+  "Boundary: a relative path expands to an absolute directory path."
