You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: archive_windows_test.go
    path of file: ./repos/moby/pkg/archive
    
    the code of the file until where you have to start completion: //go:build windows

package archive // import "github.com/docker/docker/pkg/archive"

import (
	"os"
	"path/filepath"
	"testing"
)

func TestCopyFileWithInvalidDest(t *testing.T) {
	// TODO Windows: This is currently failing. Not sure what has
	// recently changed in CopyWithTar as used to pass. Further investigation
    
func TestCanonicalTarName(t *testing.T) {
	cases := []struct {
		in       string
		isDir    bool
		expected string
	}{
		{"foo", false, "foo"},
		{"foo", true, "foo/"},
		{`foo\bar`, false, "foo/bar"},
		{`foo\bar`, true, "foo/bar/"},
	}
	for _, v := range cases {
		if canonicalTarName(v.in, v.isDir) != v.expected {
			t.Fatalf("wrong canonical tar name. expected:%s got:%s", v.expected, canonicalTarName(v.in, v.isDir))
		}
	}
}
