- MediaSourceTestRunner aims to encapsulate some of the logic currently used in DynamicConcatenatingMediaSourceTest, so it can be re-used for testing other MediaSource implementations. - The change also fixes DynamicConcatenatingMediaSourceTest to execute calls on the correct threads, and to release handler threads at the end of each test. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=176117535
