У меня есть ионное приложение, мне нужно написать модульный тест для этой страницы.Я новичок в Жасмин.как написать контрольный пример для следующих методов
import { Component, EventEmitter, Input, OnInit, Output } from '@angular/core';
import { MarketingPreference } from '../../models/marketing-preference';
import { PreferencesService } from '../../providers/authentication/preferences.service';
import { CommonConstants } from '../../providers/common.constants';
import { UtilService } from './../../providers/util.service';
@Component({
selector: 'marketing-preferences-content',
templateUrl: 'marketing-preferences-content.html'
})
export class MarketingPreferencesContent implements OnInit {
listPreferences: MarketingPreference[];
@Input() loginEnrollmentFlow: boolean;
@Output() preferencesSubmittedSuccess: EventEmitter<any> = new EventEmitter();
@Output() preferencesSubmittedError: EventEmitter<any> = new EventEmitter();
constructor(private preferencesService: PreferencesService, private utilService: UtilService) {}
ngOnInit(): void {
this.preferencesService
.getPreferences('marketing')
.then(({ preferences }) => {
this.listPreferences = preferences;
})
.catch(() => {
this.utilService.showAlert('', CommonConstants.ErrorMessages.SERVER_DOWN, CommonConstants.Buttons.OK);
});
}
checkBoxListener(e: HTMLInputElement, index: number): void {
this.listPreferences[index].election = e.checked ? CommonConstants.Application_Variables.YES : CommonConstants.Application_Variables.NO;
}
updatePreferences(): void {
this.preferencesService
.postPreferences({ preferences: this.listPreferences })
.then(() => {
this.preferencesSubmittedSuccess.emit(this.listPreferences);
})
.catch(error => {
this.preferencesSubmittedError.emit(error);
});
}
}
Мои спецификации.ts
import { CUSTOM_ELEMENTS_SCHEMA } from '@angular/core';
import { async, ComponentFixture, TestBed } from '@angular/core/testing';

import { CommonConstants } from '../../providers/common.constants';
import { MarketingPreference } from '../../models/marketing-preference';
describe('MarketingPreferencesContent', () => {
let fixture: ComponentFixture<MarketingPreferencesContent>;
let component: MarketingPreferencesContent;
let mockUtilService: UtilService;
let mockPreferencesService: PreferencesService;
beforeEach(async(() => {
mockUtilService = jasmine.createSpyObj('utils', ['showAlert']);
mockPreferencesService = jasmine.createSpyObj('preferencesService', ['getPreferences', 'postPreferences']);
TestBed.configureTestingModule({
declarations: [MarketingPreferencesContent],
schemas: [CUSTOM_ELEMENTS_SCHEMA],
providers: [
{ provide: UtilService, useValue: mockUtilService },
{ provide: PreferencesService, useValue: mockPreferencesService }

});
fixture = TestBed.createComponent(MarketingPreferencesContent);
component = fixture.componentInstance;
}));
it('should create the component instance', async(() => {
expect(component).toBeDefined();
}));
});
