Overview

Note:

the test user API is fairly slow compared to other interfaces (which makes sense – it’s creating whole new user accounts!).

Create and manage test users for your application. A test user is a user account associated with an app created for the purpose of testing the functionality of that app. You can use test users for manual or automated testing – Koala’s live test suite uses test users to verify the library works with Facebook.

See developers.facebook.com/docs/test_users/.

Constructor Details

#initialize(options = {}) ⇒ TestUsers

Create a new TestUsers instance. If you don’t have your app’s access token, provide the app’s secret and Koala will make a request to Facebook for the appropriate token.

Options Hash (options):

  • :app_id (Object) —

    the application’s ID.

  • :app_access_token (Object) —

    an application access token, if known.

  • :secret (Object) —

    the application’s secret.

Raises:

  • ArgumentError if the application ID and one of the app access token or the secret are not provided.

#befriend(user1_hash, user2_hash, options = {}) ⇒ Object

Note:

there’s no way to unfriend test users; you can always just create a new one.

Make two test users friends.

#create(installed, permissions = nil, args = {}, options = {}) ⇒ Object

  @api.graph_call(test_user_accounts_path, args, "post", options)
end

#create_network(network_size, installed = true, permissions = '', options = {}) ⇒ Object

Note:

this call slows down dramatically the more users you create (test user calls are slow, and more users => more 1-on-1 connections to be made). Use carefully.

Create a network of test users, all of whom are friends and have the same permissions.

#delete_all(options = {}) ⇒ Object

Note:

if you have a lot of test users (> 20), this operation can take a long time.

Deletes all test users in batches of 50.
