istanbul + mocha runs but stalls before the first test- why?

I have a large set of regression tests for the backend server.
Those tests no longer run to completion an fail at the first test.
This project grew out of the angular-starter project being built with webpack. The project runs well, but the regression tests not longer function.

The test in the server is run using (testServer.sh):

#!/usr/bin/env bash
find . -name "*.js" -type f -delete
rm -rf coverage
tsc
export NODE_ENV='test'
export ...
...
istanbul cover --config='test.istanbul.yml' --report html _mocha -- -- $(find . -path ../node_modules -prune -o -name '*.spec.js');
../node_modules/.bin/remap-istanbul -i coverage/coverage.json -o coverage-final -t html;
echo 'all done:'


find . -path ../node_modules -prune -o -name '*.spec.js' lists:

./api/user/user.controller.spec.js
./api/user/user.model.spec.js
./api/user/index.spec.js
...
...
./auth/local/local.spec.js
./email/email.spec.js


where the first test set comes from './api/user/user.controller.spec.js'.

This first test (user.controller.spec.ts) is:

import * as chai from 'chai';
import * as sinonChai from 'sinon-chai';
import log, error from '../../logging';
import mocha from 'mocha';
import * as app from '../../app';
import Token from '../user/token';
import * as userController from './user.controller';
import * as auth from '../../auth/auth.service';
import * as mongodb from 'mongodb';
import User from '../../api/user';
import UserData from '../../api/user';

chai.use(sinonChai);
const expect = chai.expect;
import * as request from 'supertest';
const users = User.getUsers();

describe('user.controller test', function ()

const admin_id = new mongodb.ObjectID('55148df6935c4bac084b30b2'); // JoelParke
const user_id = new mongodb.ObjectID('580bc41993b35207fd6c2263'); // joel@dynazu
const textangular_id = new mongodb.ObjectID('55a1baa2521bc91832f2450a');
const sample_id = new mongodb.ObjectID('5547e7520845397b4ff2eb18');
const icalAdmin = 'ZzO1xCPTB14qJrknRIXAkvRtWIqBewbEiH6dipFF.ics?nocache';
let accessTokenAdminUser: string;

this.timeout(10000);

before( (done: mocha.Done) =>

log('app setup');
app.start().then((res) =>
log('all setup and ready to test');
done();
);

);

it('checkSharingFromUsers success', (done: mocha.Done) =>
users.findOne(_id: admin_id)
.catch((err2: any) =>
throw err2;
)
.then((__user: UserData) =>
userController.checkSharingFrom(__user, textangular_id)
.then((result) =>
expect(result.found).equals(result.bWrite).equals(true);
done();
);
);
);

it('... success', (done: mocha.Done) => ... );
....
....

);


Running ./testServer.sh gives output from the call to app.start():

BUT - I never see any log messages beyond the initial ones generated by the server starting up in app()
Setting verbose:true in test.istanbul.yml and running ./testServer.sh gives:

This output is followed by the log messages from my server as it is instantiated (as shown above).

But I never see any other messages. After waiting a longtime, and hitting a ^C gives:
(because I have enabled handle-sigint: true in test.istanbul.yml)

So for some reason the test is hanging. But it is unclear to me why this is, or how to debug this.

If you have any insight it would be greatly appreciated!!

NOTE: I have checked that the server is listening on the assigned port: 9000 as expected:
tcp6 0 0 :::9000 :::* LISTEN 1088/node
