ATest: Extend dry-run features to test runner level.

The "--dry-run" option now runs in test_runner level and provides the running commands
of the target tests without actually building/installing/testing them, while previously
it was implemented in test_finder level and shared the same function with option "--info".

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
