angular - 命名空间 'jasmine' 没有导出成员 'SpyObj'

Question

我正在尝试为我的测试创建一个 spy 对象:

let spy: jasmine.SpyObj<GeneralService>;

不幸的是，我在运行 ng test 时遇到了这个错误:

Namespace 'jasmine' has no exported member 'SpyObj'

此外，WebStorm 将 SpyObj 标记为未解析的变量。

这是来 self 的 package.json 的 devDependencies:

"devDependencies": {
    "@angular/cli": "1.7.3",
    "@types/jasmine": "2.5.36",
    "@types/node": "7.0.27",
    "jasmine": "~2.4.1",
    "jasmine-core": "~2.4.1",
    "karma": "^1.7.1",
    "karma-chrome-launcher": "^2.2.0",
    "karma-cli": "^1.0.1",
    "karma-jasmine": "^1.1.1",
    "karma-jasmine-html-reporter": "^0.2.2",
    "karma-phantomjs-launcher": "^1.0.2",
    "lodash": "4.16.2",
    "ts-node": "1.3.0",
    "tslint": "^3.15.1",
    "typescript": "2.6.2"
  }

更新:

我引用了 Angular 测试文档: https://angular.io/guide/testing

let masterService: MasterService;
let valueServiceSpy: jasmine.SpyObj<ValueService>;

beforeEach(() => {
  const spy = jasmine.createSpyObj('ValueService', ['getValue']);

  TestBed.configureTestingModule({
    // Provide both the service-to-test and its (spy) dependency
    providers: [
      MasterService,
      { provide: ValueService, useValue: spy }
    ]
  });
  // Inject both the service-to-test and its (spy) dependency
  masterService = TestBed.get(MasterService);
  valueServiceSpy = TestBed.get(ValueService);
});

我最终将 spy 配置为 any:

 let spy: any;

您的 jasmine 版本不支持以后版本中引入的 SpyObj 类型。

尝试将 jasmine-core 和 @types/jasmine 从 package.json 更新到最新的稳定版本或尝试使用 "jasmine-core": "2.8.0", @types/jasmine": "2.6.0" 应该可以正常工作，没有错误。
