• 간단해지는 코드 , syntax sugar
• 클래스 , 상속 , 모듈 구성 ⇒ 아키텍처 진화
• 브라우저들 지원 계속
• 결국엔 표준 , transpiler 는 거쳐갈 뿐

ngMock vs. ngMockE2E
The ngMock module provides support to inject
and mock Angular services into unit tests. In
addition, ngMock also extends various core ng
services such that they can be inspected and
controlled in a synchronous manner within test
code.
The ngMockE2E is an angular module which
contains mocks suitable for end-to-end testing.
Currently there is only one mock present in this
module - the e2e $httpBackend mock.
ngMock ngMockE2E
Fake HTTP backend implementation suitable for end-to-end testing or backend-less development of applications that use the $http service.
Fake HTTP backend implementation suitable for unit testing applications that use the $http service.
