Typescript 如何使用 runInInjectionContext 中的参数测试功能性路由防护

我正在实现一个Angular 为15.2.9的functional router guard，它判断用户是否已登录.如果不是这样，警卫应该返回false或UrlTree(即重定向到登录页面)，具体取决于参数redirectToLogin: boolean.

我正在使用一个工厂函数来实现功能路由守卫，它类似于百分之一:

export const isLoggedIn = (redirectToLogin: boolean): CanActivateFn => {
  return (next: ActivatedRouteSnapshot, state: RouterStateSnapshot) => {
    const isLoggedIn = !!inject(CookieService).check('some_cookie');

    if (isLoggedIn) return true;
    if (!isLoggedIn && !redirectToLogin) return false;

    const redirectUrl = inject(Router).createUrlTree(['user', 'sign_in'], {
      queryParams: { next: encodeURIComponent(`/${next.url.join('/')}`) },
      queryParamsHandling: 'merge',
    });
    return redirectUrl;
  };
};

它像预期的那样工作，但我不能为它写specs:

  let cookieServiceSpy;
  let activatedRouteSnapshot;

  beforeEach(() => {
    cookieServiceSpy = jasmine.createSpyObj<CookieService>(['check']);
    activatedRouteSnapshot = { url: [], data: {} };
    TestBed.configureTestingModule({
      providers: [
        isLoggedIn,
        { provide: CookieService, useValue: cookieServiceSpy },
        {
          provide: ActivatedRouteSnapshot,
          useValue: activatedRouteSnapshot,
        },
      ],
    });
  });

  it('should return true when secure_user_id cookie is present and redirectToLogin is false', () => {
    // given
    cookieServiceSpy.check.and.returnValue(true);
    activatedRouteSnapshot.data.redirectToLogin = false;
    // when
    const result = TestBed.runInInjectionContext(isLoggedIn); // <-- this line is the problem
    // then
    expect(result).toBeTrue();
  });

导致打字错误:Argument of type '(redirectToLogin: boolean) => CanActivateFn' is not assignable to parameter of type '() => CanActivateFn'. Target signature provides too few arguments. Expected 1 or more, but got 0.

我还try 了其他几种 Select :

• TestBed.runInInjectionContext(isLoggedIn as any)个➔Can't resolve all parameters for isLoggedIn: (?).正在试运行
• TestBed.runInInjectionContext(isLoggedIn(false))%Argument of type 'CanActivateFn' is not assignable to parameter of type '() => boolean | UrlTree | Observable<boolean | UrlTree> | Promise<boolean | UrlTree>'. Target signature provides too few arguments. Expected 2 or more, but got 0.
• TestBed.runInInjectionContext(isLoggedIn(false) as any)个➔Can't resolve all parameters for isLoggedIn: (?).正在试运行
• TestBed.runInInjectionContext(isLoggedIn(false)(activatedRouteSnapshot, null))%Argument of type 'boolean | UrlTree | Observable<boolean | UrlTree> | Promise<boolean | UrlTree>' is not assignable to parameter of type '() => unknown'. Type 'boolean' is not assignable to type '() => unknown'.
• TestBed.runInInjectionContext(isLoggedIn(false)(activatedRouteSnapshot, null) as any);%inject() must be called from an injection context such as a constructor, a factory function, a field initializer, or a function used with 101.
• TestBed.runInInjectionContext(isLoggedIn(false) as any)(activatedRouteSnapshot, null);%This expression is not callable. Type '{}' has no call signatures.
• (TestBed.runInInjectionContext(isLoggedIn(false) as any) as any)(activatedRouteSnapshot, null)%Can't resolve all parameters for isLoggedIn: (?).

我还try 省略工厂函数，并使用Routing Data作为参数，如图here所示，但注入ActivatedRouteSnapshot是不可能的，使用ActivatedRoute会产生嵌套的可观察对象……一定有一种更简单的方法.

How can I test the functional router guard?个
