branch: master
commit c0462e120d064cb5943b31a9c8dfec1c62712a9f
Author: Michael Albinus <address@hidden>
Commit: Michael Albinus <address@hidden>

    Some fixes in filenotify-tests.el for cygwin
    
    * test/lisp/filenotify-tests.el (file-notify--test-timeout):
    Reintroduce value for cygwin, it's needed on slow systems.
    (file-notify--wait-for-events): Move up definition.
    (file-notify--test-no-descriptors): Use `file-notify--wait-for-events'.
    (file-notify--test-with-events-check, file-notify--test-with-events)
    (file-notify-test08-watched-file-in-watched-dir):
    Use :random rather than `random.
    (file-notify-test06-many-events): Do not skip for cygwin.
