Exec single test (it) or single describe by command line

[nicolalandro]

I need the possibility to exec only one test, because acceptance test is slow and I need to manage one test only when I find a problem.

There seems to be support for those

I want to exec one test without touch the code only specify the name or the path from the "describe" to the "it".
