      (with-current-buffer (popup-test-helper-get-overlays-buffer)

    (insert (make-string (- (window-width) 1) ? ))
    (let ((popup (popup-tip "Margin?" :nowait t :margin t)))
      (with-current-buffer (popup-test-helper-get-overlays-buffer)
        (let ((points (popup-test-helper-match-points '(" Margin? "))))
          (should (every #'identity points))
          (should (equal (car (popup-test-helper-points-to-columns points))
                         (- (window-width) 9)))
