Jest does not exit after running end-to-end app test

[tamias]

Expected Behavior

Jest exits after running end-to-end app test.

Actual Behavior

Jest displays the following message and does not exit.

Jest did not exit one second after the test run has completed.

This usually means that there are asynchronous operations that weren't stopped in your tests. Consider running Jest with `--detectOpenHandles` to troubleshoot this issue.

Steps to Reproduce the Problem

1. Replace nestjs-redis (github:skunight/nestjs-redis#939f33a7) with @liaoliaots/nestjs-redis.
2. Update code accordingly; update imports and, if using @liaoliaots/nestjs-redis v5, use RedisManager instead of RedisService.
3. Run app end-to-end test.

Specifications

• Version: @liaoliaots/nestjs-redis 5.1.0 & 3.1.1,
• Platform: Docker using node:12.16.2-alpine image

app.e2e-spec.ts:

import { AppModule } from '../src/app.module';
import { INestApplication } from '@nestjs/common';
import { Test, TestingModule } from '@nestjs/testing';
import request from 'supertest';

describe('AppController (e2e)', () => {
  let app: INestApplication;

  beforeAll(async () => {
    const moduleFixture: TestingModule = await Test.createTestingModule({
      imports: [AppModule],
    }).compile();

    app = moduleFixture.createNestApplication();
    await app.init();
  });

  afterAll(async () => {
    await app.close();
  });

  it('/ (GET)', () => request(app.getHttpServer()).get('/').expect(200).expect('Hello World!'));
});

Test output:

You can try to set closeClient option to true and try it again.
