[chore] integration test for mac

[tkmct]

on macos, I could run integration tests by applying following configs. but this might break other os.

I hope we can add some conditions like
getContainer returns 0.0.0.0 when the os is macos. I think we can refer this doc https://nodejs.org/api/process.html#process_process_platform

i agree with wanseob's comment. we can make this works for more general situation

[tkmct]

okay, I'll work on that. thanks!
