Test assertion may be unpredictable

HI, i was looking at this test:

test('should return 200 and apply the default query options', async () => {
      await insertUsers([userOne, userTwo, admin]);

      const res = await request(app)
        .get('/v1/users')
        .set('Authorization', `Bearer ${adminAccessToken}`)
        .send()
        .expect(httpStatus.OK);

      expect(res.body).toEqual({
        results: expect.any(Array),
        page: 1,
        limit: 10,
        totalPages: 1,
        totalResults: 3,
      });
      expect(res.body.results).toHaveLength(3);
      expect(res.body.results[0]).toEqual({
        id: userOne._id.toHexString(),
        name: userOne.name,
        email: userOne.email,
        role: userOne.role,
      });
    });

More in detail at this part:

expect(res.body.results[0]).toEqual({
        id: userOne._id.toHexString(),
        name: userOne.name,
        email: userOne.email,
        role: userOne.role,
      });
    });

It seems to me that you can't be sure that the first element is userOne, because there is no default sorting provided and mongo don't ensures a default sort. Am I wrong?
Maybe you can do:

expect(res.body.results).toContainEqual({
        id: userOne._id.toHexString(),
        name: userOne.name,
        email: userOne.email,
        role: userOne.role,
      });
    });

You're right. Thanks a lot. I fixed it by adding a default sort order (based on createdAt) in the paginate plugin.
