OS collects system level operations that need to be mocked out during tests.

type RealOS

type RealOS struct{}

RealOS is used to dispatch the real system level operations.

func (RealOS) CopyFile

func (RealOS) CopyFile(src, dest string, perm os.FileMode) error

CopyFile copys src file to dest file

func (RealOS) MkdirAll

func (RealOS) MkdirAll(path string, perm os.FileMode) error

MkdirAll will will call os.MkdirAll to create a directory.

func (RealOS) Mount

func (RealOS) Mount(source string, target string, fstype string, flags uintptr, data string) error

Mount will call unix.Mount to mount the file.

func (RealOS) OpenFifo

func (RealOS) OpenFifo(ctx context.Context, fn string, flag int, perm os.FileMode) (io.ReadWriteCloser, error)

OpenFifo will call fifo.OpenFifo to open a fifo.

func (RealOS) RemoveAll

func (RealOS) RemoveAll(path string) error

RemoveAll will call os.RemoveAll to remove the path and its children.

func (RealOS) Stat

func (RealOS) Stat(name string) (os.FileInfo, error)

Stat will call os.Stat to get the status of the given file.

func (RealOS) Unmount

func (RealOS) Unmount(target string, flags int) error

Unmount will call unix.Unmount to unmount the file. The function doesn't return error if target is not mounted.

func (RealOS) WriteFile

func (RealOS) WriteFile(filename string, data []byte, perm os.FileMode) error

WriteFile will call ioutil.WriteFile to write data into a file.
