我的代码服务:
describe('Component: Auth', () => {
let component: AuthService;
let fixture: ComponentFixture<AuthService>;
beforeEach(() => {
TestBed.configureTestingModule({
declarations: [AuthService]
})
fixture = TestBed.createComponent(AuthService);
component = fixture.componentInstance;
});
});

你能问我,这是什么问题?
如下使用:
服务应该是providers数组。
describe('Component: Auth', () => {
let component: AuthService;
let fixture: ComponentFixture<AuthService>;
beforeEach(() => {
TestBed.configureTestingModule({
declarations: [],
providers: [AuthService] // **Like this.**
})
fixture = TestBed.createComponent(AuthService);
component = fixture.componentInstance;
});
});
