 // Package testing provides support for automated testing of Go packages.
 // It is intended to be used in concert with the ``go test'' command, which automates
 // execution of any function of the form
 //     func TestXxx(*testing.T)
 // where Xxx can be any alphanumeric string (but the first letter must not be in
 // [a-z]) and serves to identify the test routine.
