Functions

func CreateDummyBuf

func CreateDummyBuf(size int64) []byte

CreateDummyBuf creates a byte slice that is `size` big. It's filled with the repeating numbers [0...254].

func CreateFile

func CreateFile(size int64) string

CreateFile creates a temporary file in the systems tmp-folder. The file will be `size` bytes big, filled with content from CreateDummyBuf.

func CreateRandomDummyBuf

func CreateRandomDummyBuf(size, seed int64) []byte

CreateRandomDummyBuf creates data that is evenly distributed and therefore notirously hard to compress.

func DumbCopy

func DumbCopy(dst io.Writer, src io.Reader, useReadFrom, useWriteTo bool) (written int64, err error)

DumbCopy works like io.Copy but may be instructed to not use WriteTo or ReadFrom

func Remover

func Remover(t *testing.T, paths ...string)

Remover removes all files in paths recursively and errors when it fails. It is no error if there's nothing to delete. It's useful in defer statements.
