+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.
