_Asynchronous assert fails in Mocha you can see and don't timeout_

[![License:MIT](https://img.shields.io/badge/License-MIT-blue.svg)](https://github.com/center-key/assert-deep-strict-equal/blob/main/LICENSE.txt)

[![npm](https://img.shields.io/npm/v/assert-deep-strict-equal.svg)](https://www.npmjs.com/package/assert-deep-strict-equal)

[![Build](https://github.com/center-key/assert-deep-strict-equal/actions/workflows/run-spec-on-push.yaml/badge.svg)](https://github.com/center-key/assert-deep-strict-equal/actions/workflows/run-spec-on-push.yaml)

## A) Setup

Install package for node:

```shell

$ npm install --save-dev assert-deep-strict-equal

```

Import into your Mocha spec file:

```javascript

import { assertDeepStrictEqual } from 'assert-deep-strict-equal';

```

## B) Usage

```javascript

const actual =   { ingredient: 'sugar', units: 'grams', amount: 100 };

const expected = { ingredient: 'sugar', units: 'grams', amount: 100 };

assertDeepStrictEqual(actual, expected, done);

```

The third parameter for the `done` callback is optional:

```javascript

assertDeepStrictEqual(actual, expected);  //synchronous test case

```

## C) Example

```javascript

describe('Star Wars API result for spaceship #3', () => {

   it('is a Star Destroyer', (done) => {

      const url = 'https://swapi.py4e.com/api/starships/3/';

      const handleData = (data) => {

         const actual = {

            name:         data.name,

            model:        data.model,

            manufacturer: data.manufacturer,

            };

         const expected = {

            name:         'Star Destroyer',

            model:        'Imperial I-class Star Destroyer',

            manufacturer: 'Kuat Drive Yards',

            };

         assertDeepStrictEqual(actual, expected, done);

         };

      fetchJson.get(url, { format: 'json' }).then(handleData);

      });

   });

```

Commands to run the above **Star Destroyer** example and others in [examples.spec.js](examples.spec.js):

```shell

$ cd assert-deep-strict-equal

$ npm install

$ npm run examples

```



Note that the assertion failure does _not_ cause a timeout and the test case error is easy to see and interpret. 

The value of the `name` field is `"BOGUS!"` (red), but it was expected to be `"payapa-berry"` (green).
