Better way of mocking the injected repository about typeorm-typedi-extensions HOT 2 OPEN

// base.repository.ts
import { EntityTarget, Repository as Repo } from 'typeorm';
import { dataSource } from '..';

export const Repository = <Entity>(target: EntityTarget<Entity>) => {
	return class extends Repo<Entity> {
		constructor() {
			super(target, dataSource.createEntityManager());
		}
	};
};

// user.repository.ts
import { Service } from 'typedi';
import { User } from '../entities';
import { Repository } from './base.repository';

@Service()
export class UserRepository extends Repository(User) {
	findByEmailOrFail(email: string) {
		return this.findOneByOrFail({ email });
	}
}
