 # java-racingcar-precourse
+
+### 🔑 기능 정리
+
+1. 사용자에게 자동차 경주할 자동차 이름들과 경주 차수를 받는다.
+2. 경주 차수 동안 n대의 자동차가 조건에 따라, 전진 또는 멈춘 상황을 출력한다.
+3. 게임이 끝난 후 가장 멀리 이동해 우승한 자동차를 출력한다.
+
+---
+
+### ✅ 구현 조건
+
+#### 입력 조건
+
+자동차 이름
+
+- [ ] 경주할 자동차 이름과 경주 차수 2가지 입력 필요
+- [ ] 자동차 이름은 `,` 기준으로 구분
+- [ ] 자동차 이름은 1자 이상 5자 이하만 가능함
+- [ ] 사용성을 고려해 자동차 이름에 공백이 있는 경우 없는 것으로 처리함
+
+경주 차수
+
+- [ ] 경주 차수는 숫자여야 함
+- [ ] 경주 차수는 양의 정수여야 함
+- [ ] 사용자가 잘못된 값을 입력한 경우 `IllegalArgumentException`을 발생 후 종료되어야 함
+
+#### 동작 조건
+
+- [ ] 경주는 1명이서 할 수 없음
+- [ ] 입력된 경주 차수 동안 n대의 자동차는 전진 또는 멈출 수 있음
+    - [ ] 전진 조건: 0 ~ 9 사이에서 추출한 무작위 값이 4 이상인 경우
+- [ ] 각 경주마다 각 자동차의 이동 결과를 출력
+- [ ] 우승자는 한 명 이상일 수 있음
+    - [ ] 우승 조건: 가장 많이 전진한 자동차
+
+#### 출력 조건
+
+- [ ] 자동차 이름은 `,` 기준으로 구분
+- [ ] 전진하는 자동차를 출력할 때마다, 전진한 자동차 이름과 이동거리를 출력 (ex `pobi : --`)
+- [ ] 자동차 경주 게임 완료 후, 누가 우승했는지 출력 (ex `최종 우승자 : pobi`)
+- [ ] 공동 우승자의 경우 `,`를 기준으로 출력 (ex `최종 우승자 : pobi, jun`)
+- [ ] 우승자 출력 시, 입력 순서로 출력해야 함
+
+---
+
+### 🚨 예외(IllegalArgumentException) 발생 조건
+
+- 잘못된 값을 입력한 경우 예외 발생
+- 입력해야 하는 값: `자동차 이름`, `경주 차수`
+
+자동차 이름
+
+1. 자동차 이름이 공백이면 예외 발생
+2. 자동차 이름은 5자 초과면 예외 발생
+3. 자동차 이름 중복 입력 시 예외 발생
+4. 자동차 이름 목록에 이름이 1개일 경우 예외 발생
+
+경주 차수
+
+1. 경주 차수에 공백 입력 시 예외 발생
+2. 경주 차수에 숫자가 아닌 값 입력 시 예외 발생(`NumberFormatException`이 발생하는 경우)
+3. 경주 차수에 0 입력 시 예외 발생
+4. 경주 차수에 음수 입력 시 예외 발생
+
+---
+
+### 🧪 테스트 목록
+
+##### **CarTest**
+
+* [ ] 성공: 이름 길이 1~5자 허용, 생성 가능
+* [ ] 성공: 이동 조건 충족 시 위치 1 증가
+* [ ] 성공: 이동 조건 미충족 시 위치 유지
+* [ ] 실패: 이름이 공백이거나 5자 초과면 예외 발생 → `IllegalArgumentException`
+
+---
+
+##### **CarsTest**
+
+* [ ] 성공: 여러 자동차 동시에 이동 가능
+* [ ] 성공: 라운드 진행 시 이동 거리 누적
+* [ ] 실패: 자동차 리스트 비어있음 → `IllegalArgumentException`
+* [ ] 실패: 자동차 1대만 입력 → `IllegalArgumentException`
+* [ ] 실패: 이름 중복 → `IllegalArgumentException`
+
+---
+
+##### **RandomMovePolicyTest**
+
+* [ ] 성공: 랜덤값 4 이상이면 실제 정책에서 true 반환 가능
+
+---
+
+##### **WinnerCalculatorTest**
+
+* [ ] 성공: 최대 이동 거리 계산 및 우승자 필터링
+* [ ] 실패: 자동차 리스트 비어있음 → `IllegalArgumentException`
+
+---
+
+##### **RacingServiceTest**
+
+* [ ] 성공: 자동차 이름 입력 후 trim 적용
+* [ ] 성공: 양의 정수 경주 차수 설정 가능
+* [ ] 성공: 여러 라운드 후 위치 누적
+* [ ] 성공: 우승자 리스트 반환, 입력 순서 유지
+* [ ] 실패: 자동차 이름 입력 null/공백 → `IllegalArgumentException`
+* [ ] 실패: 경주 차수 0, 음수, 숫자 아님 → `IllegalArgumentException`
+
+---
+
+### 📑 구현 순서
+
+#### 1. 기본 세팅
+
+    - jdk 21 버전 설정
+    - java style guide 설정
+
+#### 2. 경주할 자동차 이름, 경주 차수 입력받기
+
+    - readLine() 으로 문자열 입력 받기
+    - 경주할 자동차 이름 및 경주 차수 입력 유효성 검사 (예외 발생 조건 참고)
+    - 경주할 자동차 이름의 경우 , 기준으로 분할해 입력 처리하기
+
+#### 3. 실행 결과 출력하기
+
+    - 0~9 사이의 수를 랜덤하게 뽑고, 4 이상인 경우 전진으로 처리(그 외는 멈춤으로 처리)
+    - 전진 여부 확인 후 전진한 횟수 증가시키기
+    - 경주 차수만큼 실행 결과 출력하기
+
+#### 4. 최종 우승자 발표하기
+
+    - 1명인 경우 그냥 출력 / 다수인 경우 , 로 구분하여 출력
+
+---
+
+### 📄 예시 입출력
+
+```
+경주할 자동차 이름을 입력하세요.(이름은 쉼표(,) 기준으로 구분)
+pobi,woni,jun
+시도할 횟수는 몇 회인가요?
+3
+
+실행 결과
+pobi : -
+woni : 
+jun : -
+
+pobi : --
+woni : -
+jun : --
+
+pobi : ---
+woni : --
+jun : ---
+
+최종 우승자 : pobi, jun
+```
