원격 호스트에서 명령을 실행해보십시오 (3 번째)

Robot Framework 사용해보기①
하고 싶은 것의 3번째:vyos→vyos2에의 ping을 실행해 100% 성공하는 것을 확인한다에 도전한다.

show version 때와 같은 느낌으로 갈 것 같다.
우선 수동.

좋아 PASS했다.

그리고 timeout 값을 늘리면 괜찮습니다.

Timeout
Argument timeout is used by Read Until variants. The default value is 3 seconds. See time
format below for supported timeout syntax.



Time format
All timeouts, delays or retry intervals can be given as numbers considered seconds (e.g. 0.5 or 42) or in Robot Framework's time syntax (e.g. 1.5 seconds or 1 min 30 s). For more information about the Time syntax .

데포 3s로 변경도 할 수 있을 것 같다.

응? ? ? 효과가 없다. . . 왠지 장절한 착각하고 있니? ? ?
타임 아웃 초과의 메세지는 Test timeout exceeded 라고 쓰고 있지만 출력 다르다. . .
google 선생님에게 물어봐도 가르쳐주지 마. . . .

포기하는 것도 필요할까.

그 밖에 사용할 수 있을 것 같은 것을 치트 시트로 찾으자. . .

Builtin에는 sleep 있다.

ping 실행하고 나서 저장 기다리면 좋을까?
