使用TypeMoq Mock和Angular TestBed

我按如下方式定义了一个Fooservice

import {InjectablE} from "@angular/core";
export interface Foo {
    Foo(): String;
}

@Injectable()
export class Fooservice implements Foo {
    Foo(): String {
        return "Fooey!";
    }
}

和像这样的BarComponent

import {Component} from "@angular/core";
import {FooservicE} from "./foo.service";

@Component({
    modulEID: 'module.id',template: '<h1>Bar Component</h1>'
})
export class BarComponent {
    constructor(private fooservice: FooservicE) {}

    doFoo(): String {
        return(this.fooservice.Foo());
    }
}

现在我想测试我的BarComponent,我想使用TypeMoq来模拟Fooservice,所以@R_720_10673@下

import * as TypeMoq from 'typemoq';
import {Foo,FooservicE} from "./foo.service";
import {TESTBed,async} from "@angular/core/tesTing";
import {BarComponent} from "./bar.component";

describe('BarComponent',() => {
    let component: BarComponent;
    let mockFooservice: TypeMoq.Imock<Foo>;

    beforeEach(async(() => {
        mockFooservice = TypeMoq.mock.ofType<Foo>();
        TESTBed.configureTesTingModule({
            declarations: [BarComponent],providers: [{ provide: Fooservice,useValue: mockFooservice.object}]
        });
    }));

    beforeEach(() => {
        let fixture = TESTBed.createComponent(BarComponent);
        component = fixture.componenTinstance;
    });

    it('does something',() => {
        mockFooservice.setup(x => x.Foo()).returns(() => "FooBar!");
        expect(component.doFoo()).toEqual("FooBar!");
    });

});

但是,运行上面的命令会出现以下错误

是否可以将TypeMoq与角度TESTBed一起使用,如果是这样,你如何正确地做到这一点？

providers: [{ provide: Fooservice,useValue: mockFooservice.object}]

providers: [{ provide: Fooservice,useFactory: () => { return mockFooservice.object } }]
