Change to root when pulling coverage files off the device in the test
result listener. This allows collecting coverage data without requiring
tests run as root.

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

If you are a tests writer you should start looking in the test_framework/ component which contains everything needed to write a tests in Tradefed.
