ReferenceError：之后未定义（SELENIUM + JEST）

Question

今天，我开始通过Selenium WebDriver进行测试，但是遇到了这个问题（错误）：

ReferenceError: after is not defined

我设法从after和Jasmine库中发现Mocha是全局变量。但是我还是不能做任何事情。

我的单元测试是使用Jest进行的，我不想将其更改为Mocha。

测试（基本）看起来像这样（google_search_test.js）：

const {Browser, By, Key, until} = require('selenium-webdriver');
const {ignore, suite} = require('selenium-webdriver/testing');

suite(function(env) {
  describe('Google Search', function() {
    let driver;

    beforeEach(async function() {
      driver = await env.builder()
        .forBrowser('chrome')
        .build();
    });

    it('demo', async function() {
      await driver.get('https://www.google.com/ncr');
      await driver.findElement(By.name('q')).sendKeys('webdriver', Key.RETURN);
      await driver.wait(until.titleIs('webdriver - Google Search'), 1000);
    });

    ignore(env.browsers(Browser.CHROME)).it('demo 2', async function() {
      await driver.get('https://www.google.com/ncr');
      await driver.wait(until.urlIs('https://www.google.com/'), 1500);
    });

    after(() => driver.quit());
  });
});

Package.json看起来像这样：
