Functions

func TestRenameFS

func TestRenameFS(fsys fs.FS, tmpDir string) error

TestRenameFS tests a wfs.RenameFS implementation. It assumes the filesystem also implements wfs.WriteFileFS so it can stage source files. tmpDir is a directory the test may freely create and destroy entries under.

func TestWriteFileFS

func TestWriteFileFS(fsys fs.FS, tmpDir string) error

TestWriteFileFS tests a wfs.WriteFileFS implementation.

Typical usage inside a test is:

tmpDir, err := os.MkdirTemp("", "test")
if err != nil {
  t.Fatal(err)
}
defer os.RemoveAll(tmpDir)

fsys := osfs.New(filepath.Dir(tmpDir))
if err := wfstest.TestWriteFileFS(fsys, filepath.Base(tmpDir)); err != nil {
  t.Fatal(err)
}
