Last updates on the code files was (currently) 2 years ago.
I cloned the repo and ran npm i. This gives me multiple warnings that packages are deprecated and reports 39 vulnerabilities (8 critical, 21 high). "npm audit fix" does not fix that.
Running the app ("npm start") results in errors:
"error digital envelope routines::unsupported opensslErrorStack:
[ 'error:03000086:digital envelope routines::initialization error' ],
library: 'digital envelope routines',
reason: 'unsupported',
code: 'ERR_OSSL_EVP_UNSUPPORTED'
}"
(OpenSSl had some CVE's which were patched, and I assume the JS/TS library versions predate those.)

Running npm test also results in the same error, but caused by the karma server: [karma-server: UnhandledRejection: Error digital envelope routines::unsupported
I have a fully updated Win11 x64 machine , w node.js 18.14.2, npm 8.12.2, (globally) angular CLI 15.2.4

Hello,

I downloaded this angular project

Executed the code "npm install npm test"

Executed another code "ng test"

I get 0 specs.

What part am I missing?

Is it possibly that you can update this source code to angualr 10 and apply it again at your github profile?

Thank you!

Fresh clone of the repo on my machine produces a failure on npm install. The error message is one I would expect if the node-sass repo was blocked by a proxy (I've encountered this at work), but I'm on a personal machine and network for this so I'm confused as to why it's happening. It appears to be this issue and just the version of some package or another is pointing to an unavailable node-sass version. Regardless, the details and error are below. I do not have this problem when creating new Angular app, so I wonder if version bumping this repo would solve it, but that can be challenging for sure. I'm going to try to continue the course using a WSL 2 Ubuntu instance and see how that goes.

I know the spec files are created during the demo, but have them as a reference point would be helpful.

I run into this error following the course at Pluralsight. All tests (11 so far) pass, but this error is thrown in the terminal (webstorm).

This concerns chapter 4, mocking child components.

My code:

import {ComponentFixture, TestBed} from '@angular/core/testing';
import {HeroesComponent} from './heroes.component';
import {HeroService} from '../hero.service';
import {Component, EventEmitter, Input, NO_ERRORS_SCHEMA, Output} from '@angular/core';
import {of} from 'rxjs/internal/observable/of';
import {Hero} from '../hero';
import {By} from '@angular/platform-browser';

describe('HeroesComponent', () => {
  let fixture: ComponentFixture<HeroesComponent>;
  let mockHeroService;
  let HEROES;

  @Component({
    selector: 'app-hero',
    template: '<div></div>',
  })
  class FakeHeroComponent {
    @Input() hero: Hero;
    // @Output() delete = new EventEmitter();
  }

    beforeEach(() => {
    HEROES = [
      {id: 1, name: 'SpiderDude', strength: 8},
      {id: 2, name: 'Wonderful Woman', strength: 24},
      {id: 3, name: 'SuperDude', strength: 55}
    ];
    mockHeroService = jasmine.createSpyObj(['getHeroes', 'addHero', 'deleteHero']);
    TestBed.configureTestingModule({
      declarations: [HeroesComponent, FakeHeroComponent],
      providers: [
        { provide: HeroService, useValue: mockHeroService }
      ]
      // schemas: [NO_ERRORS_SCHEMA]    // ignore child component
    });
    fixture = TestBed.createComponent(HeroesComponent);
  });

  it('should set heroes correctly from the service', () => {
    mockHeroService.getHeroes.and.returnValue(of(HEROES));
    fixture.detectChanges();
    expect(fixture.componentInstance.heroes.length).toBe(3);
  });

  it('should create one li for each hero', () => {
    mockHeroService.getHeroes.and.returnValue(of(HEROES));
    fixture.detectChanges();
    expect(fixture.debugElement.queryAll(By.css('li')).length).toBe(3);
  });
});

I am getting this error which performing npm install

Im having troubles running the angular unit test project on multiple machines... Maybe you have a lot of global installs that i dont. My friend are having the excact same problem.
npm i runs without problems
npm start => Cannot find module 'webpack'
Error: Cannot find module 'webpack'
at Function.Module._resolveFilename (module.js:547:15)

running npm i webpack i can move on but are stopped by:
ENOENT... cannot find jquery.min.js (in fact node_modules holds no jquery folder at all after npm i)
running npm i jquery and then npm start brings me to
ENOENT ... cannot find toastr.min.js
another install and start later
ENOENT ... cannot find bootstrap.js
npm i bootstrap finally brings me to:
ERROR in multi ./node_modules/toastr/build/toastr.min.css ./node_modules/ngf-bootstrap/dist/bootstrap.min.css ./src/styles.css

so i give up...

I should mention that i have run dkuratas beginning ngrx and several other ng-courses on plural without any problems
