 1. Copy over test binary to /data/local on device.

[frankf, 2013/06/11 02:50:15]

This doc is pretty out-dated. Let's get rid of it.

[gkanwar, 2013/06/12 01:27:32]

Done.

 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
+loaded. We don't care about the rare testcases which succeeded on emulator, but
 failed on device.
