This question is a follow up to #3810.

[REQUIRED] Question

We are developing a lib that wraps around exoplayer. It is somewhat hard to write unit test for Player.EventListener, for example, without loading a real video, thread sleeping, etc. From #3810 I noticed there's a way to emulate portions of exoplayers's behavior and was wondering if the way to go would be for us to just copy your testutil classes or if there are plans to expose them as actual testing libs, analogous to spring-test, that provides helpers and stubs for http function.

This issue does not seem to follow the issue template. Make sure you provide all the required information.

I don't see anything speaking against publishing these modules as they are.

Note that we are unlikely to provide new features just for testing external usages though. If you want to get started on unit tests involving the full player, please have a look at ExoPlayerTest for example, which uses ExoPlayerTestRunner.

Code prepared for publication. I leave this issue open until we actually ensured it's available on jCenter

This has been requested (for 2.11.0). It's pending approval, and will hopefully be available soon.
