I'm sorry. the above comment was not drawn in details.

I show you what I did.

Firstly I downloaded Android 4.0.3 R3 Compatibility Test Suite (CTS) from the following google site. http://source.android.com/compatibility/downloads.html

then I constructed CTS and SDK in my PC and connected 2 device to my PC.

I executed the commands as below.

1. ./android-cts/tool/cts-tradefed
2. run -plan CTS --shards 2

Consequently, the following message was shown.

cts-tf>10-23 18:xx:xx I/unknown_devices: Created result dir 2012.10.xx._xx.xx.xx Android CTS 4.0.3_r3 I/Device Manager : Detected new device a61xxxxx I/Device Manager : Detected new device de0xxxxx

but after that, no message was shown.

Answer 1

You won't see test status output on the console when sharding. You can use the '-l debug' option to 'run cts' to see debug information.

For example:

run cts --plan CTS --shards 2 -l debug

If you input the above command in console, you can see all the activities going on your 2 devices. Like installing the testrunner apks, running the tests and uninstalling the apks after tests.

Answer 2

Add the device id's of the connected devices.

Command to get the device ID : adb devices

Update device ID and run the below command:

run -plan CTS --shards 2 --serial <device id1> --serial <device id2>
