Test script to test connect and disconnect sequence between two devices which can run
SL4A. The script does the following:
  Setup:
    Clear up the bonded devices on both bluetooth adapters and bond the DUTs to each other.
  Test (NUM_TEST_RUNS times):
    1. Connect A2dpSink and HeadsetClient
      1.1. Check that devices are connected.
    2. Disconnect A2dpSink and HeadsetClient
      2.1 Check that devices are disconnected.
