## 1. React Native 프로젝트에서 Jest의 주요 역할은 무엇입니까?

**답변**

Jest는 React Native에 기본으로 포함된 JavaScript 테스팅 프레임워크입니다. 테스트 실행, 어서션, 모킹, 코드 커버리지를 처리합니다. 특정 측면에 특화된 다른 도구들과 달리, Jest는 React Native에 네이티브로 통합된 완전한 솔루션을 제공합니다.

## 2. React Native Testing Library(RNTL)의 주요 기능은 무엇입니까?

**답변**

React Native Testing Library는 구현 세부 사항이 아니라 사용자 동작에 초점을 맞춘 테스트를 권장합니다. 사용자가 하듯이(텍스트, 접근 가능한 역할, 플레이스홀더로) 컴포넌트를 조회하는 유틸리티를 제공하여, 내부 리팩토링에 더 강한 테스트를 만듭니다.

## 3. 'Submit' 텍스트가 있는 버튼을 선택할 때 우선해야 할 RNTL 조회 메서드는 무엇입니까?

**답변**

getByText는 보이는 텍스트를 찾아 사용자가 하듯이 요소를 선택하므로 권장되는 메서드입니다. 이 접근 방식은 테스트를 더 직관적이고 견고하게 만듭니다. getByTestId는 testID 속성을 추가해야 하며 실제 사용자 동작을 반영하지 않습니다.
