FakeStdio can be used to fake stdin and capture stdout. Between creating a new FakeStdio and calling ReadAndRestore on it, code reading os.Stdin will get the contents of stdinText passed to New. Output to os.Stdout will be captured and returned from ReadAndRestore. FakeStdio is not reusable; don't attempt to use it after calling ReadAndRestore, but it should be safe to create a new FakeStdio.

func New() (*FakeStdOutErr, error)

func (sf *FakeStdOutErr) ReadAndRestore() ([]byte, []byte, error)
