如何使用Selenium和JavaScript计算'li‘元素的数量并断言它们的数量？

const { Builder, By, Key, until } = require('selenium-webdriver');
const driver = new Builder().forBrowser('chrome').build();

await driver.get('https://example.com');

const liElements = await driver.findElements(By.xpath('//li'));
const liCount = liElements.length;

const liElements = await driver.findElements(By.css('li'));
const liCount = liElements.length;

const assert = require('assert');
assert.equal(liCount, 5, "The count of 'li' elements is not as expected.");

await driver.quit();
