Research direction

Start with the AndroidX test orchestrator instrumentation-result handling and the reported testCollection.txt output; reproduce the Application.onCreate() crash using the documented adb command on API 29. Trace why the recorded crash details are not reflected in the final instrumentation output, and consider the issue done when the process crash is reported as a test failure rather than OK (0 tests).

Description

Description

My code changes caused exception at Application.onCreate(), and instrumented tests run via AndroidX test orchestrator.

execution command line like:

// prepare AndroidX test orchestrator
....

adb shell 'CLASSPATH=$(pm path androidx.test.services) app_process / androidx.test.services.shellexecutor.ShellMain am instrument -w -r -e coverageFilePath coverage_files/ -e useTestStorage true -e coverage true -e clearPackageData true -e targetInstrumentation com.mypackage.test/androidx.test.runner.AndroidJUnitRunner androidx.test.orchestrator/.AndroidTestOrchestrator'
INSTRUMENTATION_RESULT: stream=

Time: 0

OK (0 tests)


INSTRUMENTATION_CODE: 0

And there is one details file at adb shell run-as androidx.test.orchestrator cat /data/user_de/0/androidx.test.orchestrator/files/testCollection.txt.
