How to set Golang's log output back to console?

Question

Google Go's log package has SetOutput - a function for setting the log output to any io.Writer. After I set it for testing, I would like to revert the output back to the standard console output - how do I do that? I don't see any obvious way of resetting it in the log or io packages.

Answer 1

For standard error (the default):

log.SetOutput(os.Stderr)

For standard output:

log.SetOutput(os.Stdout)
