Sto sviluppando un repository github (con angular 7 e angular-cli), e ho alcuni test con Karma e Jasmine che lavorano nel ramo master.
Ora sto cercando di aggiungere la funzione di caricamento pigro, il fatto è che i test che prima venivano superati, ora non lo fanno. È divertente perché solo i test del modulo di caricamento lento falliscono ...
Ecco il codice e l'errore:
import {async, TestBed} from '@angular/core/testing';
import {APP_BASE_HREF} from '@angular/common';
import {AppModule} from '../../app.module';
import {HeroDetailComponent} from './hero-detail.component';
describe('HeroDetailComponent', () => {
beforeEach(async(() => {
TestBed.configureTestingModule({
imports: [AppModule
],
providers: [
{provide: APP_BASE_HREF, useValue: '/'}
],
}).compileComponents();
}));
it('should create hero detail component', (() => {
const fixture = TestBed.createComponent(HeroDetailComponent);
const component = fixture.debugElement.componentInstance;
expect(component).toBeTruthy();
}));
});
L'errore è questo:
Chrome 58.0.3029 (Mac OS X 10.12.6) HeroDetailComponent should create hero detail component FAILED
Error: Illegal state: Could not load the summary for directive HeroDetailComponent.

Puoi vedere l'intero progetto, per maggiori dettagli se ne hai bisogno.
AGGIORNAMENTO: aggiunta dichiarazione come questa:
beforeEach(async(() => {
TestBed.configureTestingModule({
imports: [
AppModule
],
declarations: [HeroDetailComponent],
providers: [
{provide: APP_BASE_HREF, useValue: '/'}
],
}).compileComponents();
}));
Ora vengono visualizzati nuovi errori:
The pipe 'translate' could not be found ("<h1 class="section-title">{{[ERROR ->]'heroDetail' | translate}}</h1>
<md-progress-spinner *ngIf="!hero"
class="progre"): ng:///DynamicTestModule/HeroDetailComponent.html@0:28
Can't bind to 'color' since it isn't a known property of 'md-progress-spinner'.
E altro ancora ... è come se tutte le direttive e i componenti del materiale angolare e il tubo translate da ngx-translate / core non sembrassero essere inclusi ...
AGGIORNATO: SOLUZIONE FINALE
Il problema era che HeroesModule non era stato importato da nessuna parte. Funziona, perché HeroesModule dichiara HeroDetailComponent, che era il problema iniziale :
import {async, TestBed} from '@angular/core/testing';
import {APP_BASE_HREF} from '@angular/common';
import {AppModule} from '../../app.module';
import {HeroDetailComponent} from './hero-detail.component';
import {HeroesModule} from '../heroes.module';
describe('HeroDetailComponent', () => {
beforeEach(async(() => {
TestBed.configureTestingModule({
imports: [
AppModule,
HeroesModule
],
providers: [
{provide: APP_BASE_HREF, useValue: '/'}
],
}).compileComponents();
}));
it('should create hero detail component', (() => {
const fixture = TestBed.createComponent(HeroDetailComponent);
const component = fixture.debugElement.componentInstance;
expect(component).toBeTruthy();
}));
});
