你做了什么？

这些修改后的测试失败了：
archive/tar :

func TestWriterAddFS(t *testing.T) {
	fsys := fstest.MapFS{
		"emptyfolder":          {Mode: 0755 | os.ModeDir},
		"file.go":              {Data: []byte("hello")},
		"subfolder":            {Mode: 0755 | os.ModeDir},
		"subfolder/another.go": {Data: []byte("world")},
	}
	var buf bytes.Buffer
	tw := NewWriter(&buf)
	if err := tw.AddFS(fsys); err != nil {
		t.Fatal(err)
	}
	if err := tw.Close(); err != nil {
		t.Fatal(err)
	}

	// Test that we can get the files back from the archive
	tr := NewReader(&buf)

	names := make([]string, 0, len(fsys))
	for name := range fsys {
		names = append(names, name)
	}
	sort.Strings(names)

	entriesLeft := len(fsys)
	for _, name := range names {
		entriesLeft--

		entryInfo, err := fsys.Stat(name)
		if err != nil {
			t.Fatalf("getting entry info error: %v", err)
		}
		hdr, err := tr.Next()
		if err == io.EOF {
			break // End of archive
		}
		if err != nil {
			t.Fatal(err)
		}

		if hdr.Name != name {
			t.Fatalf("test fs has filename %v; archive header has %v",
				name, hdr.Name)
		}

		if entryInfo.Mode() != hdr.FileInfo().Mode() {
			t.Fatalf("%s: test fs has mode %v; archive header has %v",
				name, entryInfo.Mode(), hdr.FileInfo().Mode())
		}

		if entryInfo.IsDir() {
			continue
		}

		data, err := io.ReadAll(tr)
		if err != nil {
			t.Fatal(err)
		}
		origdata := fsys[name].Data
		if string(data) != string(origdata) {
			t.Fatalf("test fs has file content %v; archive header has %v",
				data, origdata)
		}
	}
	if entriesLeft > 0 {
		t.Fatalf("not all entries are in the archive")
	}
}

archive/zip :

func TestWriterAddFS(t *testing.T) {
	buf := new(bytes.Buffer)
	w := NewWriter(buf)
	tests := []WriteTest{

		},
		{
			Name: "subfolder/another.go",
			Data: []byte("world"),
			Mode: 0644,
		},
	}
	err := w.AddFS(writeTestsToFS(tests))
	if err != nil {
		t.Fatal(err)
	}

	if err := w.Close(); err != nil {
		t.Fatal(err)
	}

	// read it back
	r, err := NewReader(bytes.NewReader(buf.Bytes()), int64(buf.Len()))
	if err != nil {
		t.Fatal(err)
	}
	for i, wt := range tests {
		testReadFile(t, r.File[i], &wt)
	}
}
