The UserTuneIntegrationTest, in rapid succession:
- add a listener for PEP-published usertune data
- publishes a usertune
- waits for a notification to arrive
Implicit to adding the listener is the publication of a change in
Pubsub notification filtering. This can involve a stanza handshake,
as CAPS is involved.
A race condition exists where the usertune data can be published
before the notification filter has been properly applied.
The changes in this commit add a synchronzation point that ensures
that the notification filter is in place, before the usertune data
is published.
