testing: B.Run

[jezek]

go version: go1.6.2 linux/386

Sorry, if this is not relevant, but I can not find answer to this issue:

In documentation the testing pakage has function B.Run(...)
https://golang.org/pkg/testing/#B.Run

But compiler gives me error, that it is undefined.

Am I missing something? why it is in doc and not implemented?
