In order to run these tests you need to have a phone running SUT Agent connected.
Make sure you can reach the device's TCP 20700 and 20701 ports. Doing adb forward tcp:20700 tcp:20700 && adb forward tcp:20701 tcp:20701 will forward your localhost 20700 and 20701 ports to the ones on the device.
You might need some common tools like cp. Use the setup-tools.sh script to install them. It requires $ADB to point to the adb binary on the system.
Make sure the SUTAgent on the device is running.
Run: python runtests.py
