People listed as Admins, Developers or Testers within the Roles section of your app dashboard can fully test the app, and request any permissions, without submitting it for review.
However, you must have your integration reviewed before launching your app to real people (people not listed in the Roles section) if you want to request the publish_action permission from them. The only permissions which do not require review are public_profile, email and user_friends.
As you're the developer of the app - you should be able to grant yourself publish_actions without any problems.
