I have a User creation function like this that uses the returning() function. I want to mock test it but don't know what to pass in below. 
public async createUser(userData: CreateUserDto): Promise<User> {
    if (isEmpty(userData)) throw new HttpException(400, "You're not userData");

    const findUser: User = await DB.query.users.findFirst({
      where: eq(users.email, userData.email),
    });

    if (findUser)
      throw new HttpException(
        409,
        `You're email ${userData.email} already exists`,
      );

    const hashedPassword = await hash(userData.password, 10);
    const createdUser: User = (
      await DB.insert(users)
        .values({
          ...userData,
          password: hashedPassword,
        })
        .returning()
    )[0];

    return createdUser;
  }
public async createUser(userData: CreateUserDto): Promise<User> {
    if (isEmpty(userData)) throw new HttpException(400, "You're not userData");

    const findUser: User = await DB.query.users.findFirst({
      where: eq(users.email, userData.email),
    });

    if (findUser)
      throw new HttpException(
        409,
        `You're email ${userData.email} already exists`,
      );

    const hashedPassword = await hash(userData.password, 10);
    const createdUser: User = (
      await DB.insert(users)
        .values({
          ...userData,
          password: hashedPassword,
        })
        .returning()
    )[0];

    return createdUser;
  }
describe('[POST] /users', () => {
    it('response Create user', async () => {
      const userData: CreateUserDto = {
        password: 'q1w2e3r4!',
      };

      const usersRoute = new UserRoute();

      drizzleMock.query.users.findFirst.mockResolvedValueOnce(null);
      drizzleMock.insert.mockReturnValueOnce(???);

      const app = new App([usersRoute]);
      return request(app.getServer())
        .post(`${usersRoute.path}`)
        .set('Authorization', `Bearer ${tokenData.token}`)
        .send(userData)
        .expect(201);
    });
  });
