-1. Copy over test binary to /data/local on device.
-2. Resources: chrome/unit_tests requires resources (chrome.pak and en-US.pak)
-   to be deployed to the device. We use the device's $EXTERNAL_STORAGE as the
-   base dir (which maps to Context.getExternalFilesDir()).
-3. Environment:
-3.1. chrome/unit_tests requires (via chrome_paths.cc) a directory named:
-     $EXTERNAL_STORAGE + /chrome/test/data
-4. Run the binary in the device and stream the log to the host.
-4.1. Optionally, filter specific tests.
-4.2. If we're running a single test suite and we have multiple devices
-     connected, we'll shard the tests.
-5. Clean up the device.
-
-Suppressions:
-
-Individual tests in a test binary can be suppressed by listing it in
-the gtest_filter directory in a file of the same name as the test binary,
-one test per line. Here is an example:
-
-  $ cat gtest_filter/base_unittests_disabled
-  DataPackTest.Load
-  ReadOnlyFileUtilTest.ContentsEqual
-
-This file is generated by the tests running on devices. If running on emulator,
-additonal filter file which lists the tests only failed in emulator will be
-loaded. We don't care about the rare testcases which succeeded on emuatlor, but
-failed on device.
