[Testing] Can't resolve all parameters for MockDevToolsExtension

[Mokto]

Hi !

This is a...

• [x] bug report
• [x] usage question

What toolchain are you using for transpilation/bundling?

• [x] angular/cli

Environment

NodeJS Version: 8.9 Typescript Version: 2.4.2 Angular Version: 5 @angular-redux/store version: 7.0.2 angular/cli version: (if applicable) : 1.6.3 OS: Mac

Issue:

Hi, when trying to test a component having a redux actions service, I get Can't resolve all parameters for MockDevToolsExtension

Here is my piece of code (i followed the instructions here) :

import { async, ComponentFixture, TestBed } from '@angular/core/testing';
import { NgReduxTestingModule, MockNgRedux } from '@angular-redux/store/testing';

import { LoginComponent } from './login.component';
import { UserActions } from '../../redux/user';

describe('LoginComponent', () => {
  let component: LoginComponent;
  let fixture: ComponentFixture<LoginComponent>;

  beforeEach(async(() => {
    TestBed.configureTestingModule({
      declarations: [ LoginComponent ],
      imports: [NgReduxTestingModule],
      providers: [UserActions],
    })
    .compileComponents();

    MockNgRedux.reset();
  }));

  beforeEach(() => {
    fixture = TestBed.createComponent(LoginComponent);
    component = fixture.componentInstance;
    fixture.detectChanges();
  });

  it('should create', () => {
    expect(component).toBeTruthy();
  });
});

Conclusion

I'm not sure how to solve this. Do not hesitate if you need more informations.

Thanks !

I'm having the same issue with a near identical setup (only difference is running TypeScript version 2.6.2 and on Windows, also Angular 5). Have there been any updates? Cheers!

Hi all, just commenting again to mention I fixed this issue by upgrading Angular to version 7.
