Can not specify the org when doing rest:target,rest:login tests

[jianghaitao]

Maybe I am missing something obvious here, please excuse me if that is the case.

I tried to run the test like following

-rest:space=test -workload=rest:target,rest:login -iterations=10 -concurrency=1

I am a developer in org test and space test. But above keep tell me that it can not find the space test. Is there a way to specify the org?

cf target already shows that I am targeted and login into org test and space test.

I can run -workload=cf:push etc.

Thanks
