Trying to use swc for e2e tests to see what's the performance speedup

nb: swc can't tell that an enum imported from another module is an enum so the type would be undefined
Typeorm can't tell what type to assign and assigns undefined
you must specify the type manually, explore the api to find the valid values

nb2: swc doesn't like
import * as request from "supertest"

import request from "supertest" works just as well
does it work for all this kind of modules? idk
