在Jest中，当被测试的函数不使用异步/等待时，我可以使用异步/等待吗？

const addUserController = function (req, res, next) {
    Users.addOne(req.userid, req.body.email)
    .then(() => {
      res.status(202).send();
    .catch((err) => {
      console.log(err);
      res.status(500).json({ message: "Internal server error." });
};

it("Should add a user", () => {
    let req, res, next, pool;
    pool = new Pool();
    req = httpsMocks.createRequest();
    res = httpsMocks.createResponse();
    res.next = null;
    req.userid = 1;
    req.body = {
      id: 2
    pool.query.mockResolvedValue({rows:[], rowCount: 1});
    apiController.addUserController(req, res, next);
    expect(res.statusCode).toBe(202);
    expect(pool.query).toBeCalledTimes(1);
});

it("Should add a user", async () => {
    let req, res, next, pool;
    pool = new Pool();
    req = httpsMocks.createRequest();
    res = httpsMocks.createResponse();
    res.next = null;
    req.userid = 1;
    req.body = {
      id: 2
    pool.query.mockResolvedValue({rows:[], rowCount: 1});
    await apiController.addUserController(req, res, next);
    expect(res.statusCode).toBe(202);
    expect(pool.query).toBeCalledTimes(1);
});

apiController.addUserController(req, res, next);
await undefined;

it("Should add a user", async () => {
    const { once, EventEmitter } = require('events');
    const pool = new Pool();
    const req = httpsMocks.createRequest();
    const res = httpsMocks.createResponse({ eventEmitter: EventEmitter });
    res.next = null;
    req.userid = 1;
    req.body = {
      id: 2
    pool.query.mockResolvedValue({rows:[], rowCount: 1});
    const responseEndPromise = once(res, 'end');
