Wait for script to start and until file is pulled

When we execute the prefetto script, make sure we wait until the
perfetto script actually began the tracing. this will allow us to have a
tracefile even when the test finishes quickly. Also make sure to wait
until the trace process has finished, instead of a random 5s wait.

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
