Trade Federation (TF / tradefed)

TF is a test harness used to drive Android automated testing. It runs on test hosts and monitors the connected devices, handling test scheduling & execution and device management.

Other test harnesses like Compatibility Test Suite (CTS) and Vendor Test Suite (VTS) use TF as a basis and extend it for their particular needs.

Building TF:

source build/envsetup.sh
tapas tradefed-all
make -j8
