const addUserController = function (req, res, next) {
    Users.addOne(req.userid, req.body.email)
    .then(() => {
      res.status(202).send();
    .catch((err) => {

      res.status(500).json({ message: "Internal server error." });

    pool = new Pool();
    req = httpsMocks.createRequest();

    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 () => {
