Types

type IOStreams

type IOStreams struct {
	// In think, os.Stdin
	In io.Reader
	// Out think, os.Stdout
	Out io.Writer
	// ErrOut think, os.Stderr
	ErrOut io.Writer
}

IOStreams provides the standard names for iostreams. This is useful for embedding and for unit testing. Inconsistent and different names make it hard to read and review code.

func NewTestIOStreams

func NewTestIOStreams() (IOStreams, *bytes.Buffer, *bytes.Buffer, *bytes.Buffer)

NewTestIOStreams returns a valid IOStreams and in, out, errout buffers for unit tests.

func NewTestIOStreamsDiscard

func NewTestIOStreamsDiscard() IOStreams

NewTestIOStreamsDiscard returns a valid IOStreams that just discards.

func NewTestIOStreamsForPipe

func NewTestIOStreamsForPipe() IOStreams
