Since Tradefed event-unbalanced issue has been fixed, Atest can now raise TradeFedExitError
when encountering real unbalanced(unpaired) events.

BUG: 120114859
BUG: 119239432

Test: 1. ./atest_run_unittests.py
         The unittest of test_process_event_not_balanced() in atest_tf_test_runner_unittest.py
      2. (a) vi cts/tests/autofillservice/src/android/autofillservice/cts/AuthenticationActivity.java
             add the following lines to let it crash.
	     private void doIt() {
             if (true) {
                 throw new IllegalStateException("ATEST, Y U NO RECOVER?");
             }
         (b) atest  CtsAutoFillServiceTestCases
             Then, atest should run normally without stopping.

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
