使用 ADB 运行 android 测试时如何获取日志

如何解决使用 ADB 运行 android 测试时如何获取日志

我使用 ADB 在多个设备上并行运行测试：

adb -s 11.11.11.111:5555 shell "CLAsspATH=$(pm path androidx.test.services) app_process / androidx.test.services.shellexecutor.ShellMain am instrument -r -w -e targetInstrumentation com.my.app.debug.test/androidx.test.runner.AndroidJUnitRunner -e clearPackageData true  -e numShards 2 -e shardindex 0 -e debug false androidx.test.orchestrator/androidx.test.orchestrator.AndroidTestorchestrator" &
adb -s 11.11.11.112:5555 shell "CLAsspATH=$(pm path androidx.test.services) app_process / androidx.test.services.shellexecutor.ShellMain am instrument -r -w -e targetInstrumentation com.my.app.debug.test/androidx.test.runner.AndroidJUnitRunner -e clearPackageData true  -e numShards 2 -e shardindex 1 -e debug false androidx.test.orchestrator/androidx.test.orchestrator.AndroidTestorchestrator" &
wait

如果测试失败，通常会显示错误消息/堆栈跟踪，但并非总是如此。因此，将应用程序的日志保存在文件中会很有帮助。测试完成后，我尝试了以下命令：

adb -s 11.11.11.111:5555 logcat | grep "com.my.app.*" > app/build/reports/logcat.txt

但是该命令只保存文件中的系统日志，而不是我在 Android Studio 中运行测试时通常可以看到的日志（在 Android Studio 的 logcat 窗口中）。

解决方法

您可能只是忘记在 adb logcat 上添加 -s 11.11.11.11x:5555 选项。
