如何使用protractor随机获取下拉列表中的元素？

 it('should select a random option from the dropdown', async () => {

   const dropdown = element(by.id('dropdownId'));

   const options = dropdown.all(by.tagName('option'));

   const optionsCount = await options.count();

   // ...

 });

const { browser, element, by } = require('protractor');

describe('Dropdown Test', () => {
  it('should select a random option from the dropdown', async () => {
    const dropdown = element(by.id('dropdownId'));
    const options = dropdown.all(by.tagName('option'));
    const optionsCount = await options.count();

    const randomIndex = Math.floor(Math.random() * optionsCount);
    await options.get(randomIndex).click();

    // Add assertions or other operations as needed
  });
});
