Types

type Directory

type Directory struct {
	// contains filtered or unexported fields
}

Directory is mock in-memory implementation of fs.Directory

func NewDirectory

func NewDirectory() *Directory

NewDirectory returns new mock directory.ds

func (*Directory) AddDir

func (imd *Directory) AddDir(name string, permissions os.FileMode) *Directory

AddDir adds a fake directory with a given name and permissions.

func (*Directory) AddFile

func (imd *Directory) AddFile(name string, content []byte, permissions os.FileMode) *File

AddFile adds a mock file with the specified name, content and permissions.

func (*Directory) AddFileLines

func (imd *Directory) AddFileLines(name string, lines []string, permissions os.FileMode) *File

AddFileLines adds a mock file with the specified name, text content and permissions.

func (*Directory) FailReaddir

func (imd *Directory) FailReaddir(err error)

FailReaddir causes the subsequent Readdir() calls to fail with the specified error.

func (Directory) IsDir

func (e Directory) IsDir() bool

func (Directory) ModTime

func (e Directory) ModTime() time.Time

func (Directory) Mode

func (e Directory) Mode() os.FileMode

func (e Directory) Name() string

func (Directory) Owner

func (e Directory) Owner() fs.OwnerInfo

func (*Directory) Readdir

func (imd *Directory) Readdir(ctx context.Context) (fs.Entries, error)

Readdir gets the contents of a directory.

func (*Directory) Remove

func (imd *Directory) Remove(name string)

Remove removes directory entry with a given name.

func (Directory) Size

func (e Directory) Size() int64

func (*Directory) Subdir

func (imd *Directory) Subdir(name ...string) *Directory

Subdir finds a subdirectory with a given name.

func (*Directory) Summary

func (imd *Directory) Summary() *fs.DirectorySummary

Summary returns summary of a directory.

func (Directory) Sys

func (e Directory) Sys() interface{}

type File

type File struct {
	// contains filtered or unexported fields
}

File is an in-memory fs.File capable of simulating failures.

func (File) IsDir

func (e File) IsDir() bool

func (File) ModTime

func (File) Mode

func (e File) Mode() os.FileMode

func (File) Name

func (e File) Name() string

func (*File) Open

func (imf *File) Open(ctx context.Context) (fs.Reader, error)

Open opens the file for reading, optionally simulating error.

func (File) Owner

func (e File) Owner() fs.OwnerInfo

func (*File) SetContents

func (imf *File) SetContents(b []byte)

SetContents changes the contents of a given file.
