我有一些需要服务的测试。我正在使用我注入UserServiceStub
的名为SettingsComponent
的存根服务,我正在测试它。我在每次测试中重置了UserServiceStub,但是,测试是异步执行的,所以当我重置我的UserServiceStub(这是一个可注入和单例类)时,其他测试已经初始化了它。我的测试很弱,断言错了: - (
我想为每个测试做同步测试或不同的UserServiceStub实例,但我不知道该怎么做......
我试图在UserServiceStub中定义一个名为reset()
的方法来重置存根服务,但因为它是异步的,所以它不起作用。另外,我使用afterEach()
方法TestBed.resetTestEnvironment()
方法执行,但它也不起作用。
我的reset()
方法:
reset() {
this.user = { IBAN: '', SWIFT: '', paypal: '', app_idioma: '' };
}
user
,并且已被其他测试覆盖我的beforeEach()
方法就是这个
let fixture: ComponentFixture<SettingsComponent>;
let settingsComponent: SettingsComponent;
beforeEach(() => {
TestBed.configureTestingModule({
declarations: [SettingsComponent],
imports: [],
providers: [
TranslateService,
AppService,
{ provide: MockBackend, useClass: MockBackend },
{ provide: HttpToolsService, useValue: HttpToolsServiceStub },
{ provide: BaseRequestOptions, useClass: BaseRequestOptions },
{ provide: UserService, useClass: UserServiceStub } // My stub UserService
]
});
fixture = TestBed.createComponent(SettingsComponent);
settingsComponent = fixture.componentInstance;
});
测试:
it('#updateSettings should doesn\'t update the user\'s settings when is wrong', fakeAsync(
inject([UserService, HttpToolsService, MockBackend],
(userService: UserServiceStub, httpToolsService: HttpToolsService, mockBackend: MockBackend) => {
userService.reset(); // It does not work...
userService.isError = true;
// However, I have reseted my user in UserServiceStub,
// this returns false because settingsComponent.getSettings().IBAN is actually 'XXX'
// instead of '' (empty) how it has to be
expect(settingsComponent.getSettings().IBAN).toBe('');
}))
);
我希望你的答案,如果你有任何问题,请问。
谢谢: - )
答案 0 :(得分:0)
你尝试过使用getter / setter吗?这样UserServiceStub.user
的价值就不会被修改(如果我理解你想要的话)。
class UserServiceStub {
// instead of:
// this.user = { IBAN: '', SWIFT: '', paypal: '', app_idioma: '' };
// use:
get user() { return { IBAN: '', SWIFT: '', paypal: '', app_idioma: '' }; }
set user(value) { /* test something here */ }
}
