Run or Debug integration test with nodeJs using typescript, Mocha, Chai and SuperTest for async/await node api-functions

I am trying to run(using command npm run test and to debug i have been used IDE Webstorm) the integration test developed using node.js written in typescript, mocha, chai and supertest for node application developed using typescript.

In before() hook function, we are making a call to the application which actually initiating service and this call are for asynchronous(used async-await) functions(from the app.ts/app.js file of node application).

But always I am getting an error like 'Error: You are not authorized to access the key in Google KMS' (i.e. in service) and plus it said 'Error: Timeout of 60000ms exceeded. For async tests and hooks, ensure "done()" is called; if returning a Promise, ensure it resolves.' , but if I ran service/application individually it is working fine. so that means while running service the async/await code for API/function call is same.

So my point is here does this happen due to timeout the async/await request while initiating service from before() hook function.

Below are code sample in test.int-test.ts file,

    import {expect} from "chai";
    const app = require('../app');
    const supertest = require('supertest');

    describe("Test model", function () {

    this.timeout(60000);

    before(async () => {
      api = supertest(await app); 
      // app is here a entry point for my service/application which runs actually service/applicaiton. 
      // This file has async-await function which makes call to third party application
      console.log('inside before: ', JSON.stringify(api));
    });

    describe('get', function () {
      it('should respond with 200 Success', async () => {
        // call to async function
       });
    });
});

and under the section script in package.json

    "scripts": {
"test": "nyc --reporter=html --reporter=text --reporter=cobertura node_modules/mocha/bin/_mocha --reporter mocha-multi-reporters --reporter-options configFile=mocha-multi-reporters.config build/test/test.int-test.js"
}

Can anybody face such a situation? that how to initiate async/await service from integration test file.

Finally I have found the solution to run and debug integration test, we need to do few changes here.

  1. Most important to timeout issue we must set timeout as 0 i.e. **this.timeout(0)**
  2. While debugging should point to .js file in mocha setup in WebStorm, do not use .ts file, as mocha hooks up .js files for running as well as debugging a test, however we can also use .ts file to run test. (https://journal.artfuldev.com/write-tests-for-typescript-projects-with-mocha-and-chai-in-typescript-86e053bdb2b6).
  3. To run, use command 'npm run name-of-test-script', mocha will hooks up .js file only.
