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，有什么问题吗？

如下所示使用它：
服务应该在providers数组中。
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;
});

您必须实例化服务：let service = new AuthService();，不需要调用"createComponent“等等。
