angular 测试哪个 returns 函数

Question

我在下面写了测试用例，但它没有涵盖这一行：() => service.getUserProfile()

export function userServiceFactory(service: UserService) {
  return () => service.getUserProfile();
}

测试：

 import * as userserv from './user.service';
  it('should call userServiceFactory function', () => {
    const spy = spyOn(userService, 'getUserProfile').and.callThrough();
    userService.getUserProfile();
    const result = userserv.userServiceFactory(userService);
    expect(spy).toHaveBeenCalled();
    expect(result).toBeDefined();
  });

Answer 1

it('should call userServiceFactory and invoke getUserProfile ', () => {
  const getUserProfileSpy = spyOn(userService, 'getUserProfile') ;
  const result = userserv.userServiceFactory(userService);
  result.call(userService.getUserProfile);
  expect(getUserProfileSpy).toHaveBeenCalled();
});
