“findOne is not a function” with jest

[acidos]

I am using sequelize mock v5 to mock User model.

// user.test.js
import User from "../models/user"; // original user model class

jest.mock("../models/user", () => () => {
    const SequelizeMock = require("sequelize-mock-v5");
    const dbMock = new SequelizeMock();
    return dbMock.define("User", { id: 111, username: "myusername" });
});

test("blabla", async () => {
    const r = await User.findOne({ where: { id:1 }});
    // expectations here
});

This gives me

TypeError: _user.default.findOne is not a function

Here is the original User model which I am trying to mock.

// /models/user.js
export default class User extends Model {...}
