我已经为我的组件编写了一个测试,并且
失败了错误:无法解析'路由器'的所有参数(?,?,?,?,?,?, ?)。确保所有参数都使用Inject或 有效的类型注释和“路由器”装饰 可注射的。
import { Component, OnInit } from '@angular/core';
import { Router, ActivatedRoute } from '@angular/router';
import { Supplier } from './supplier';
import { SupplierService } from './supplier.service';
import { AppService } from '../shared/app.service';
@Component({
moduleId: module.id,
selector: 'supplier-form',
templateUrl: './supplier-form.component.html',
styleUrls: ['./supplier-form.component.css']
})
export class SupplierFormComponent implements OnInit {
private countries: any;
private model: Supplier;
private errorMessage: string;
private submitted: boolean = false;
private active: boolean = true;
constructor(private appService: AppService, private supplierService: SupplierService, private router: Router, private route: ActivatedRoute) {
this.model = new Supplier();
this.route.params.subscribe(params => {
let id = +params['id']; // (+) converts string 'id' to a number
if (!isNaN(id))
this.supplierService.getSupplierById(id)
.subscribe(supplier => this.model = supplier, error => this.errorMessage = error);
});
}
ngOnInit() {
this.getCountries();
}
private getCountries() {
this.appService.getCountry()
.subscribe(countries => this.countries = countries.items,
error => this.errorMessage = error);
}
private navigateToHomePage(supplier) {
if (supplier) {
let link = [''];
this.router.navigate(link);
}
}
private onSubmit(): void {
this.submitted = true;
this.supplierService.saveSupplier(this.model).subscribe(
supplier => this.navigateToHomePage(supplier),
error => this.errorMessage = error);
}
}
非常简单的组件所做的就是从一个使用Http调用的服务获取国家,并在另一个也是http调用的服务上调用save方法。我用我的Mock类来嘲笑那些服务。下面是我的测试代码。
import { By } from '@angular/platform-browser';
import { DebugElement, provide } from '@angular/core';
import { disableDeprecatedForms, provideForms } from '@angular/forms';
import { Router, ActivatedRoute } from '@angular/router';
import * as Rx from 'rxjs/Rx';
import {
beforeEach, beforeEachProviders,
describe, xdescribe,
expect, it, xit,
async, inject, addProviders,
TestComponentBuilder, ComponentFixture
} from '@angular/core/testing';
import { SupplierFormComponent } from './supplier-form.component';
import { SupplierService } from './supplier.service';
import { AppService } from '../shared/app.service';
describe('Component: Supplier', () => {
var builder;
beforeEachProviders(() => {
return [
disableDeprecatedForms(),
provideForms(),
Router, ActivatedRoute,
provide(AppService, { useClass: MockAppService }),
provide(SupplierService, { useClass: MockSupplierService })
];
});
beforeEach(inject([TestComponentBuilder], (tcb) => {
builder = tcb;
}));
it('should create Supplier Component', async(() => {
/*.overrideProviders(
SupplierFormComponent,
[{ provide: AppService, useClass: MockAppService }]
)*/
builder.createAsync(SupplierFormComponent)
.then((fixture: ComponentFixture<SupplierFormComponent>) => {
fixture.detectChanges
var compiled = fixture.debugElement.nativeElement;
console.log(compiled);
})
.catch((error) => {
console.log("error occured: " + error);
});
}));
});
class MockAppService {
public name = "Injected App Service";
public fakeResponse: any = [{ "id": 1, "name": "uk" }];
public getCountry() {
return this.fakeResponse;
}
}
class MockSupplierService {
public name = "Injected Supplier Service";
saveSupplier(supplier: any): boolean {
return true;
}
}
任何想法如何用RC.4正确模拟路由器。
