Pre-add functional tests stub to notification testing

Every time a transformed notification merged, other ones
are getting merge conflict mainly because of [1]. In this
patchset, method calls and method stubs are added in order to
avoid merge conflicts in the future. In this patchset, the
currently in-queue notifications are added.
