    Pseudocode from here on..
    Modify the test names so that it looks like "package.class#method"
    CI Service should then shard the list of tests from the output and spin up N nodes, e.g. 3 nodes are spun up each with 3 tests
    In each shard 
        - Save tests to the device's SD card
        - adb shell am instrument -w -e testFile /sdcard/tmp/testFile.txt com.android.foo/com.android.test.runner.AndroidJUnitRunner
