Model not getting injected while unit/integration test

[th-tarang-sachdev]

Hello , I am facing issue for getting injected model instance in test case
here is the detail

I have test file called
inventory.service.test.ts

import { Container } from 'typedi';
import InventoryService from '../../../src/services/inventory';
import { random } from '../../util';
import express from 'express';
import loaders from '../../../src/loaders';
import Inventory from '../../../src/models/inventory';
import startServer from '../../../src/server';

let body;
beforeAll(async done => {
  // const expressApp = express();
  // await loaders({ expressApp });
  await startServer();
  body = random.inventory();
  done();
});

describe('Inventory Service', () => {
  it('should add inventory', async () => {
    const InventoryModel: typeof Inventory = Container.get('InventoryModel');
    const Logger = Container.get('logger');
    const inventoryService = new InventoryService(InventoryModel, Logger);
    const { inventory } = await inventoryService.addInventory(body);
    expect(inventory).toBeDefined();
    expect(inventory.id).toBeDefined();
    expect(inventory.title).toBe(body.title);
  });
});

when I do like above, all test cases passes.

now I am trying to start up the server in global.setup.ts file, not in beforeAll of each test case file

so I am doing like that in jest.config.ts file

// A path to a module which exports an async function that is triggered once before all test suites
  globalSetup : "./tests/jest/globalSetup.ts",

// A path to a module which exports an async function that is triggered once after all test suites
  globalTeardown : "./tests/jest/globalTearDown.ts",

and I have added 2 files

globalSetup.ts

import startServer from '../../src/server'
const globalSetup = async () => {
    await startServer();
}

export default globalSetup;

and in globalTearDown.ts

const globalTearDown = async () => {
    // will close down that server instance
}

export default globalTearDown 

when I do test now it is throwing an error like below

_ServiceNotFoundError: Service "InventoryModel" was not found, looks like it was not registered in the container. Register it by calling Container.set("InventoryModel", ...) before using service._
