I’m developing an Ionic 5 App. I was testing a component like this:
beforeEach(async(() => {
TestBed.configureTestingModule({
declarations: [HomePage],
imports: [MocksModule, IonicModule.forRoot()]
}).compileComponents();
fixture = TestBed.createComponent(HomePage);
component = fixture.componentInstance;
fixture.detectChanges();
}));
It was working fine but after I added:
<ion-button routerLink="/settings">
<ion-icon slot="icon-only" name="settings-outline"></ion-icon>
</ion-button>
The test fails with:
Failed: R3InjectorError(DynamicTestModule)[NavController -> UrlSerializer -> UrlSerializer]:
NullInjectorError: No provider for UrlSerializer!
In MocksModule
I export a stub directive as recommended in the Angular docs I believe the error is related to the implementation of RouterLink
inside IonicModule
.
