硒打开目标URL与多个空白页并行

Question

在这个简单的单元测试中，我试图打开一些URL，但是Selenium并行打开了3个空白页面

import { Builder } from 'selenium-webdriver';

describe.only('cashpad', () => {
  it('open mail', async () => {
    const driver = await new Builder().forBrowser('chrome').build();

    try {
      await driver.get('https://www.mail.com/int/');
      await driver.sleep(5000);
    } catch(err) {
      console.log(err);

    } finally {
      await driver.quit();
    }
  });
});
