Override provider in single test in nest.js e2e testing

I have e2e test of module with controller and some providers:

beforeAll(async () => {
    const moduleRef = await Test.createTestingModule({
      controllers: [TestController],
      providers: [
        TestService,
        {
          provide: getRepositoryToken(TestEntity),
          useValue: {
            find: jest.fn(async () => testDatabaseResult),
            save: jest.fn(),
          },
        },
      ],
    }).compile();

    app = moduleRef.createNestApplication();
    app.use(cookieParser());
    app.useGlobalPipes(new ValidationPipe());

    await app.init();
  });

I'm mocking here database connection by mocking TestEntity repository and it's working fine - real implementation of service gets mocked database query result. However in one single test I need to TestEntity provider use mock find function with different implementation:

find: jest.fn(async () => otherMockedTestDatabaseResult)

How can I achieve that? I want to use real implementation of TestService which under the hood uses TestEntity repository which is mocked (and I don't want to use test database). Thank you in advance for help.

Ok I've found it, I'll post answer here just for record, in case anyone would have similiar problem, because it isn't described in Nest docs (or I couldn't find it).

When you create testing module and instance of application from testing module, application object have resolve method which can be used to retrieve provider:

it('/test', async () => {
    const testRepository = await app.resolve(getRepositoryToken(TestEvent));

    testRepository.find = jest.fn(() => []);

    return request(<...>).expect(<...>);
  });
