+# 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.
+
+![drawing](setup.png)
+
+### 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
