Lorsque je lance ce test unitaire:
it('can click profile link in template', () => {
const landingPageLinkDe = linkDes[0];
const profileLinkDe = linkDes[1];
const aboutLinkDe = linkDes[2];
const findLinkDe = linkDes[3];
const addLinkDe = linkDes[4];
const registerLinkDe = linkDes[5];
const landingPageLinkFull = links[0];
const profileLinkFull = links[1];
const aboutLinkFull = links[2];
const findLinkFull = links[3];
const addLinkFull = links[4];
const registerLinkFull = links[5];
navFixture.detectChanges();
expect(profileLinkFull.navigatedTo)
.toBeNull('link should not have navigated yet');
profileLinkDe.triggerEventHandler('click', { button: 0 });
landingPageLinkDe.triggerEventHandler('click', { button: 0 });
aboutLinkDe.triggerEventHandler('click', { button: 0 });
registerLinkDe.triggerEventHandler('click', { button: 0 });
findLinkDe.triggerEventHandler('click', { button: 0 });
addLinkDe.triggerEventHandler('click', { button: 0 });
navFixture.detectChanges();
expect(landingPageLinkFull.navigatedTo).toBe('/');
expect(profileLinkFull.navigatedTo).toBe('/profile');
expect(aboutLinkFull.navigatedTo).toBe('/about');
expect(findLinkFull.navigatedTo).toBe('/find');
expect(addLinkFull.navigatedTo).toBe('/add');
expect(registerLinkFull.navigatedTo).toBe('/register');
});
Je reçois cette erreur:
zone.js: 388 Rejet de promesse non gérée: ne peut correspondre à aucun itinéraire. Segment URL: "ajouter"; Zone: ProxyZone; Tâche: Promise.then; Valeur: Erreur: ne peut correspondre à aucun itinéraire. Segment d'URL: "ajouter" (…) Erreur: ne peut correspondre à aucun itinéraire. Segment URL: "ajouter"
Le test réussit toujours, mais il serait intéressant de savoir pourquoi j'obtiens l'erreur. Je ne reçois pas l'erreur lorsque j'utilise l'application comme le ferait un utilisateur. J'ai recherché l'erreur et cela est généralement dû au fait de ne pas fournir de chemin par défaut dans les itinéraires, mais je l'ai fait.
Suis-je en train de faire quelque chose de mal pour provoquer cette erreur?

J'ai eu le même problème récemment. Cela a été provoqué par un appel à router.navigate
À l'intérieur de la méthode ngOnInit
d'un composant. Le test tentait de créer le composant, mais à l'intérieur de ngOnInit
, il tentait de s'éloigner du composant (car certaines conditions n'étaient pas remplies).
Dans mon cas, j'importe le RouterTestingModule
dans le cadre de TestBed.configureTestingModule
. Donc, pour résoudre ce problème, j'ai simplement enregistré une route avec RouterTestingModule
. Par exemple, supposez que votre appel de navigation ressemble à router.navigate(['example'])
et qu'il se résout en ExampleComponent
. Vous pouvez configurer le test comme suit:
RouterTestingModule.withRoutes([
{ path: 'example', component: ExampleComponent}
])
Faire ce qui précède a permis à mes tests de s'exécuter sans générer d'erreur Cannot match any routes
.
Pour ce que ça vaut, je pense qu'une meilleure façon serait de bloquer le routeur et de simplement confirmer que les appels appropriés à navigate
sont effectués.
Pour développer un peu la réponse de Spoida, j'ai fini par utiliser un routeur tronqué:
class RouterStub {
url = '';
navigate(commands: any[], extras?: any) { }
}
Et puis chez vos prestataires pour votre test:
providers: [
{ provide: Router, useClass: RouterStub }
// ... other providers
]
Cela a entraîné le succès de mon test unitaire et a supprimé l'erreur de console que je voyais.
