This particular component utilizes material icons.

Currently, I am delving into learning unit testing with karma (via angular cli/webpack) and have most of the configuration set up to create the component. However, I am encountering difficulties in configuring for material icons.
Here is my progress so far:

/* configuration */
import { async, ComponentFixture, TestBed } from '@angular/core/testing';
import { By } from '@angular/platform-browser';
import { DebugElement, NO_ERRORS_SCHEMA } from '@angular/core';
import { TickerDirective } from '../../directives/ticker.directive';
import { MdIconModule, MaterialModule } from '@angular/material';
import { MdIconRegistry } from '@angular/material/icon';
/* my content */
import { FoodListComponent } from './food-list.component';
import { FoodDataService } from '../../services/food-items/food-data.service';
import { FoodItem } from '../../diet/food-item';
import { WorkingData } from '../../services/working-data/working-data';
import { WorkingDataService } from '../../services/working-data/working-data.service';
describe('FoodListComponent', () => {
let component: FoodListComponent;
let fixture: ComponentFixture<FoodListComponent>;
let foodDataService: FoodItem[];
let workingDataService: WorkingData;
let de: DebugElement[];
let el: HTMLElement;
/* Stub Services */
let foodDataServiceStub = [{
name: 'test food name ..................', // purposefully long to test the ticker directive
img: './no_image.png',
description: 'test food description'
}];
let workingDataServiceStub = {
today: new Date(),
selectedDate: new Date(2016, 2, 5),
targetDate: new Date(2016, 2, 7),
data: {exercise: 'Squat'}
};
beforeEach(async(() => {
TestBed.configureTestingModule({
declarations: [ FoodListComponent, TickerDirective ],
imports: [ MaterialModule.forRoot(), MdIconModule], // unsure about this
providers: [
{ provide: FoodDataService, useValue: foodDataServiceStub },
{ provide: WorkingDataService, useValue: workingDataServiceStub } ,
MdIconRegistry // uncertain if this is correct
],
schemas: [ NO_ERRORS_SCHEMA ]
})
.compileComponents();
}));
beforeEach(() => {
fixture = TestBed.createComponent(FoodListComponent);
component = fixture.componentInstance;
/* Inject services */
foodDataService = TestBed.get(FoodDataService);
workingDataService = TestBed.get(WorkingDataService);
/* Assign Services */
component.workingData = workingDataService;
component.foods = foodDataService;
fixture.detectChanges();
de = fixture.debugElement.queryAll(By.css('span'));
el = de[0].nativeElement;
// console.log(el);
});
it('should create', () => {
expect(component).toBeTruthy();
});
it('should display the accurate food name', () => {
expect(el.textContent).toContain('test food name ..................');
});
});
Material Icons Issue
Although the ligatures of the material icons can be seen, they are not appearing correctly. I came across a suggestion to import Http but that resulted in an error.
