Overview

OutputCapture allows to capture any text written to standard out or standard error which is especially useful during testing.

Call it like:

capture := CaptureOutput(t) doSomeActionThatWritesToStdOutAndStdErr() stdOut, stdErr := capture.Close()

CaptureOutput() and capture.Close() should always come in pairs as Close() also restores the old streams
