Stack Trace/Error Message:

TypeError: Cannot read property 'getState' of null

Additional Notes:

Hi,

When I run my unit tests, I get TypeError: Cannot read property 'getState' of null Error in the terminal / console. The tests actually pass, but the errors are still confusing. Maybe this is a lack of understanding or it's an actual bug.

I am using the connect directive in this format:

<form [connect]="['shops', 'form']">
        <label>Partner ID: </label>
        <input type="number" name="shopId" ngControl ngModel/>
</form>

because I need the state to be part of a sub module path.

My .spec.ts file looks like this:

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

import { FormComponent } from './form.component';
import { ShopActions } from '../store/shops.actions';

const mockShopActions = {
    setShop: () => {
    },
    shopLoaded: () => {
    },
};

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

    beforeEach(async(() => {
        TestBed.configureTestingModule({
            imports: [
                FormsModule,
                NgReduxTestingModule,
                NgReduxFormModule
            ],
            declarations: [FormComponent],
            providers: [
                { provide: ShopActions, useValue: mockShopActions }
            ]
        }).compileComponents();

        MockNgRedux.reset();
    }));

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

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

Here is the complete Error trace:

It looks to me as if the the nested state object is not present, when the connect class cycles through the path children.

Is there a way to tell MockNgRedux what the state object should consist of? Or am I simply doing something wrong?
