Question

按钮看起来像这样

<button [routerLink]="['/account/recovery','identification']" class="btn btn-default">Back</button>

我想在点击按钮后检查网址是否已重定向到/account/recovery/identification

如果是锚标记solution is provided here。我的问题是按钮标签。

我的测试规范看起来像这样。

beforeEach(async(() => {
        let ne = new NavigationEnd(0, "/account/recovery/otp", null);       // Create a mock instance for navigation end, utilized within OnInit()
        router = {
            navigate: jasmine.createSpy('navigate'),    // to spy on the url that has been routed
            events: new Observable(observer => {        // last router event that occurred
                observer.next(ne);
            }),

        };
        TestBed
            .configureTestingModule({
                imports: [CoreModule],
                declarations: [OtpComponent],
                providers: [
                    {provide: Router, useValue: router},
                    {provide: ActivatedRoute, useValue: router},
                    {provide: Location, useClass: SpyLocation}, FormBuilder
                ],
                schemas: [NO_ERRORS_SCHEMA]
            })
            .overrideComponent(OtpComponent, {
                set: {
                    providers: [
                        {provide: MyModel, useClass: MockModel}
                    ],
                }
            })
            .compileComponents();
    }));

    beforeEach(() => {
        fixture = TestBed.createComponent(OtpComponent);
        component = fixture.componentInstance;
    });

it('Back button click on OTP screen should redirect to identification screen', async(inject([Location], (location: Location) => {

        fixture.detectChanges();

        let buttonElements = fixture.debugElement.queryAll(By.css('button'));   // fetch all the elements with button tag.

        buttonElements[0].nativeElement.click();

        fixture.detectChanges();
        fixture.whenStable().then(
            () => {
                expect(location.path()).toBe(['/account/recovery', 'identification']);     // check if url is routed to identification page after back button is clicked
            }
        );
    })));

但它没有给我我想要的结果，这就是我得到的：

Chrome 56.0.2924 (Windows 7 0.0.0) OtpComponent Back button click on OTP screen should redirect to identification screen FAILED
        Expected '' to be [ '/account/recovery', 'identification' ].

即使buttonElements[0].nativeElement.click();似乎没有用，因为没有注册点击事件。

您共享的链接中的answer也适用于按钮。这是一个plnkr。我希望有一种方法可以静态（无需点击）检查按钮上的路由器链接。我想你可以检查它的属性并检查'ng-reflect-router-link'，但这感觉很脏。 ¯\ _（ツ）_ /¯

为测试路由创建一个轻量级组件（RouterTestingModule.withRoutes([...])）。（如果测试多条路线，您可以多次使用它。）
在测试模块导入中测试路径的虚拟组件中包含Location。
导入RouterTestingModule并将其注入测试。 @Component({ template: '' }) class DummyComponent {} beforeEach(() => { TestBed.configureTestingModule({ declarations: [AppComponent, DummyComponent], imports: [ RouterTestingModule.withRoutes([ { path: 'test', component: DummyComponent } ]) ] }); }); describe('app', () => { it('should have a test button', inject([Location], (location) => { const fixture = TestBed.createComponent(AppComponent); const elem = fixture.debugElement; const button = elem.query(e => e.name === 'button'); expect(!!button).toBe(true); expect(button.nativeElement.textContent.trim()).toBe('CLICK FOR BUBBLES'); button.nativeElement.click(); fixture.detectChanges(); fixture.whenStable().then(() => { expect(location.path()).toBe('/test'); }); })); });使用模拟位置策略，以便您可以检查更改。

Config#query
