Here are the details of the EME tests and related infrastructure that CableLabs is creating and will make available to the HTML WG.

The tests will verify these EME Wiki use cases:
Simple Streaming of a Specific Title<https://www.w3.org/wiki/HTML/Media_Task_Force/EME_Use_Cases#Simple_Streaming_of_a_Specific_Title>

Tests and encrypted test content with Widevine, PlayReady and Clear key completed. Testing the tests.
Limited Concurrent Streams via Key Renewal<https://www.w3.org/wiki/HTML/Media_Task_Force/EME_Use_Cases#Limited_Concurrent_Streams_via_Key_Renewal>

Working with a CDM vendor to create appropriate license. Will then create tests.
Limited Concurrent Streams via Key Release<https://www.w3.org/wiki/HTML/Media_Task_Force/EME_Use_Cases#Limited_Concurrent_Streams_via_Key_Release>

Blocked by lack of closure on this issue in the EME spec.
Persisted License Offline<https://www.w3.org/wiki/HTML/Media_Task_Force/EME_Use_Cases#Persisted_License_.2F_Offline>

As far as we can tell, this is only supported on Chrome but we can't get it to work. Working with Chrome team.
Delete Cached Licenses<https://w3c.github.io/encrypted-media/#widl-MediaKeySession-remove-Promise-void>

Blocked by inability to create Persisted License Offline session.
Player to Ignore Cached Licenses<https://w3c.github.io/encrypted-media/#idl-def-MediaKeySession>

Blocked by inability to create Persisted License Offline session.
License/ Key Rotation<https://www.w3.org/wiki/HTML/Media_Task_Force/EME_Use_Cases#License.2FKey_Rotation>

Will simulate this session type with multi-period (different keys) contentUnder development.

The tests will use the W3C test harness. The client player is DASH.js. Protected test content will be created for clear key, Adobe, Widevine and PlayReady CDMs.
