What will be testing code for following code with vitest:

import React from 'react';

import Puzzle from $\text{'}./$boundary$\text{'}$;

import $\{$ Syllable $\}$ from $\text{'}./$model$\text{'}$;

const initialConfig: Syllable$[][]=[$

$[$new Syllable$(\text{'}$in$\text{'},0,0),$ new Syllable$(\text{'}$vis$\text{'},0,1),$ new Syllable$(\text{'}$i$\text{'},0,2),$ new Syllable$(\text{'}$ble$\text{'},0,3)],$

$[$new Syllable$(\text{'}$im$\text{'},1,0),$ new Syllable$(\text{'}$mac$\text{'},1,1),$ new Syllable$(\text{'}$u$\text{'},1,2),$ new Syllable$(\text{'}$late$\text{'},1,3)],$

$[$new Syllable$(\text{'}$af$\text{'},2,0),$ new Syllable$(\text{'}$fil$\text{'},2,1),$ new Syllable$(\text{'}$i$\text{'},2,2),$ new Syllable$(\text{'}$ate$\text{'},2,3)],$

$[$new Syllable$(\text{'}$un$\text{'},3,0),$ new Syllable$(\text{'}$der$\text{'},3,1),$ new Syllable$(\text{'}$wa$\text{'},3,2),$ new Syllable$(\text{'}$ter$\text{'},3,3)],$
