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: localstorage_test.go
    path of file: ./repos/HackBrowserData/browsingdata/localstorage
    
    the code of the file until where you have to start completion: package localstorage

import (
	"testing"

	"github.com/stretchr/testify/assert"
	"golang.org/x/text/encoding/unicode"
)

var testCases = []struct {
	in   
    
func TestLocalStorageKeyToUTF8(t *testing.T) {
	t.Parallel()
	for _, tc := range testCases {
		actual, err := convertUTF16toUTF8(tc.in, unicode.BigEndian)
		if err != nil {
			t.Error(err)
		}
		// TODO: fix this, value from local storage if contains chinese characters, need convert utf16 to utf8
		// but now, it can't convert, so just skip it.
		assert.Equal(t, tc.actual, actual, "chinese characters can't actual convert")
	}
}
