[ts-jest] Error using createMock alongside createTestingModule and @Inject('token')

[micalevisk]

this works:

useMocker(() => createMock())

---

that's because, in your example, createMock will be called like this by nestjs: createMock('fooProvider') which ends up doing new Proxy('fooProvider', ...), which leads to that error because Proxy expects a non-primitive value as a target.

@underfisk — sorry it took me a while to close the loop. Thanks for the tip, that's what I ended up doing.
