Yes, Eli mentioned this in the bug thread. I don't know how to make
these tests pass in batch mode. I modified it to something that seems
like it should pass in batch mode, but I get a size of 0x0, which
isn't what I'm going for.

This is what I tried:

(ert-deftest xdisp-tests--window-text-pixel-size () ;; bug#45748
  (with-current-buffer-window "*test*" 'display-buffer-same-window nil
    (erase-buffer)
    (insert "xxx")
    (let* ((char-width (frame-char-width))
           (size (window-text-pixel-size (get-buffer-window) t t)))
      (should (equal (/ (car size) char-width) 3)))))

Eli mentioned moving the tests to manual/redisplay-testsuite.el, which is fine.

If anyone else has an idea how to make this test work in batch mode,
I'm all ears.

Thanks,

Aaron
