How can I get a user access token for a specific facebook test user?
===

According to [Facebook Devlopers: Test Users][1], I can list the test users of my facebook app by making a request to `https://graph.facebook.com/APP_ID/accounts/test-users?access_token=APP_ACCESS_TOKEN`. The response includes a valid user access token for each user.

How can I get a valid user access token for a specific test user without downloading the whole list of test users?
