# 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
