Types

type BufferReader

type BufferReader interface {
	io.Reader
	Reset(string)
}

ApplyMockIODiscardOutputs replaces a cobra.Command output and error streams with a dummy io.Writer. Replaces and returns the io.Reader associated to the cobra.Command input stream.

type BufferWriter

type BufferWriter interface {
	io.Writer
	Reset()
	Bytes() []byte
	String() string
}
