Coverage functions with TypeORM entity is always 0

🐛 Bug Report

Coverage functions with TypeORM entity is always 0. Please see attached screenshot. I have relations decorator

@ManyToMany(type => Group, { cascade: true })

and coverage for type => Group arrow function is 0

To Reproduce

Create an entity with relations decorator

import {
  Entity,
  Column,
  PrimaryGeneratedColumn,
  ManyToMany,
  JoinTable,
} from 'typeorm';
import { Group } from '../group/group.entity';

@Entity()
export class User {
  @PrimaryGeneratedColumn()
  id: number;

  @Column({ length: 32, unique: true, readonly: true })
  uid: string;

  @ManyToMany(type => Group, { cascade: true })
  @JoinTable()
  groups: Group[];
}

Expected behavior

Function coverage should be 100%

When ManyToMany decorator is meant to trigger?

I have no idea, that has nothing to do with Jest though.

Ignoring it unless you actually execute some stuff seems like a good compromise.
