;; This elisp program illustrates the issue.

(require 'cl)
(let ((bad-hosts
       (loop for bad
	     in `("https://wrong.host.badssl.com/"
		  "https://self-signed.badssl.com/")
	     if (condition-case e
		    (url-retrieve
		     bad (lambda (retrieved) t))
		  (error nil))
	     collect bad)))
  (if bad-hosts
      (error (format "tls misconfigured; retrieved %s ok"
		     bad-hosts))
    (url-retrieve "https://badssl.com"
		  (lambda (retrieved) t))))
