Subject: bug#30745: 26.0.91; ert should macros nest strangely
Date: Wed, 07 Mar 2018 22:24:38 +0000

This reproduction with a simpler test shows that the problem is nesting.

(require 'ert)

(defun simple-test ()
  (ert-test-result-with-condition-condition
   (ert-run-test
    (make-ert-test
     :body
     (lambda () (should (eq 1 2)))))))

(princ (simple-test))

(princ "\nAnd forcibly unnested\n")

(princ
 (let ((res (simple-test)))
   (should
    (equal
     '(ert-test-failed
       ((should (eq 1 2)) :form (eq 1 2) :value nil))
     res))))


(princ "\nAnd nested\n")

(princ
 (should
  (equal
   '(ert-test-failed
     ((should (eq 1 2)) :form (eq 1 2) :value nil))
   (simple-test))))

(princ "\n")
