Thanks Nicolas for the confirmation. I am running Emacs 25.2rc2 under Windows 10 compiled with Mingw64. 2 of the failures seem to be harmless. This one is about the file system which behaves differently under Windows : F test-org-export/file-uri Test ‘org-export-file-uri’ specifications. (ert-test-failed ((should (equal "file:///local.org" (org-export-file-uri "/local.org"))) :form (equal "file:///local.org" "file://d:/local.org") :value nil :explanation (arrays-of-different-length 17 19 "file:///local.org" "file://d:/ local.org" first-mismatch-at 7))) The absolute path has the drive name. So actually not a failure. F test-org-pcomplete/keyword Test keyword and block completion. (ert-test-failed ((should (equal "#+startup: " (org-test-with-temp-text "#+start" (pcomplete) (buffer-string)))) :form (equal "#+startup: " "#+STARTUP: ") :value nil :explanation (array-elt 2 (different-atoms (115 "#x73" "?s") (83 "#x53" "?S"))))) This one is because pcomplete is used to get completion, and the completion depends on the pcomplete-ignore-case variable, which makes pcomplete ignore case for windows-nt and cygwin by default. The last one is strange: F test-org-element/link-parser Test ‘link’ parser. (ert-test-failed ((should (equal "id" (org-test-with-temp-text "[[id:aaaa]]" (org-element-property :type ...)))) :form (equal "id" "fuzzy") :value nil :explanation (arrays-of-different-length 2 5 "id" "fuzzy" first-mismatch-at 0))) This is complete non sense, because when I evaluate the test form, I actually get "id" and I have no idea where this "fuzzy" may come from. Do you also get a warning like this: Making org-entities-user local to *temp*-443480 while let-bound! in the *Messages* buffer ?
