monkeyrunner 스크립트를 통해 android에서 dd를 사용하여 더미 파일 만들기

Question

테스트 자동화를위한 스크립트 작성 : Android 장치의 내부 메모리를 채우십시오. 이 스크립트는 파이썬으로 작성되었으며 monkeyrunner를 사용하여 장치에 연결하고 명령을 실행합니다.
이렇게하려면 더미 파일을 만들어야합니다. 이 명령을 사용하면 :

subprocess.call('adb shell dd if=/dev/zero of=/storage/sdcard0/dummy/dummy_file bs=1000000000 count=1', shell = True) 

작동합니다. 더미 파일이 생성됩니다. 그러나 다음을 사용하고 싶습니다 :

device.shell('dd if=/dev/zero of=/storage/sdcard0/dummy/dummy_file bs=1000000000 count=1') 

같은 것을해야합니다. 그러나 후자는 작업이 생성되지 않습니다이 오류가 발생하는 이유

아무도 알고 있나요?

Answer 1

AdbChimpDevice은 셸 명령이 일정 시간 내에 완료되지 않고 dd 명령이이 제한을 초과하는 경우 TimeoutException을 생성합니다. subprocess 대안을 고수해야합니다.

기본 시간 초과는 5 초입니다.
