Testcafe -有没有可能在test cafe中使用多个用户角色来执行相同的测试用例？

import { Selector, Role } from 'testcafe';

const adminRole = Role('http://example.com/login', async t => {
    await t
        .typeText('#username', 'admin')
        .typeText('#password', 'password')
        .click('#login-button');
});

const userRole = Role('http://example.com/login', async t => {
    await t
        .typeText('#username', 'user')
        .typeText('#password', 'password')
        .click('#login-button');
});

fixture `My Fixture`
    .page `http://example.com`;

test('My Test', async t => {
    await t
        .useRole(adminRole)
        .click('#admin-button')
        .expect(Selector('#admin-panel').visible).ok();

    await t
        .useRole(userRole)
        .click('#user-button')
        .expect(Selector('#user-panel').visible).ok();
});
