If your Channel Owner (Administrator of the page) is also an administrator of your FB application, then you should be able to fully test the channel stream, even without going through the application review process. You should also be able to grant the role of 'Developer' in your app to your Channel Owner for this to work. After setting up the channel in the backend, you'll still have to log in on the front-end of your site using your Facebook credentials and approve the permission.
From FB
:
If your app requests this permission Facebook will have to review how your app uses it. You can grant this permission on behalf of people listed within the Roles section of your App's Dashboard without review by Facebook.

our blog post on the FB app review process
However, if you're having trouble with using a channel owner that has a role in your app, please let us know.
