# CEC VTS testing for Android TV devices
Validate HDMI CEC VTS (android.hardware.tv.cec@1.0) functionality.
### Setup:
Running these CEC VTS tests requires an Android playback, TV or audio device connected to the host machine.

### Building
From the Android root folder, after choosing the lunch combo, use `make vts` to build VTS.
### Automation
On the host machine, ensure that the [software requirements](https://codelabs.developers.google.com/codelabs/android-lab/#2) for python SDK are met.
Given the setup described above you can run tests with any of the following commands:
1. Using vts-tradefed :
```
cd $ANDROID_BUILD_TOP/out/host/linux-x86/vts/android-vts/tools
./vts-tradefed run commandAndExit vts -m VtsHalTvCecV1_0TargetTest
```
2. Using atest
```
atest VtsHalTvCecV1_0TargetTest
```
Note : atest internally handles building as well. To update the test use '-c' (clear cache) option
