[ Spring ] nGrinder를 활용한 부하 테스트 - 2 ( 시나리오 작성 및 테스트 )

개요

해당 시나리오는 저의 개인 프로젝트인 myStory 를 기반으로 테스트를 진행할 것 이며, 해당 프로젝트의 깃 주소는 해당 링크 를 참고해주세요.

시나리오 수립

• 시나리오 1 ( 게시글 )
  회원가입 -> 로그인 -> 게시글 목록 조회 -> 게시글 조회 -> 댓글 작성 -> 포스트 추천 -> 게시글 작성 -> 게시글 수정 -> 게시글 탐색 -> 게시글 삭제

• 시나리오 2 ( 모임 )
  회원가입 -> 로그인 -> 모임 목록 조회 -> 모임 생성 -> 모임 참여 -> 나의 모임 목록 조회 -> 해당 모임 상세보기 조회 -> 해당 모임 페이지 이동 -> 모임 내 예약 추가 -> 모임 내 예약 참여 -> 모임 내 예약 탈퇴 -> 모임 수정 -> 모임 상세 탐색 -> 모임 삭제

• 시나리오 3 ( 사용자 )
  회원가입 -> 로그인 -> 마이 페이지 -> 개인 정보 변경 -> 재 로그인 -> 계정 탈퇴

테스트 진행

위의 사진처럼 Groovy 라는 언어를 활용해 작성을 하고 검증 버튼을 누르면 시험적으로 1회 실행이 되며, 이는 실제 프로젝트에도 요청이 전송이 됩니다.

General error during conversion: Unsupported class file major version 61 >에러

class file major version 61은 로드 하려고 시도하고 있는 클래스 파일이 자바 17 혹은 그 이상의 버전에서 컴파일이 되었으며, 자바 17 이상에서만 사용 될 수 있을 때 발생한다고 합니다.

해결방법
JDK SDK 버전 변경 ( 버전 8 추천 )
실행시 Java HOME 지정

시나리오 1 테스트 결과

평균 MTT : 52.5ms

가장 중요한 것은 MTT(=Mean Test Time) 으로 1회 테스트 수행 시 걸리는 시간을 의미합니다. ( 단위는 ms )

MMT가 1000을 넘을 시 1초가 걸린다는 뜻인데 최소 1 이하로 줄여야 합니다.
만약 MMT가 1000이 넘어가는 부분이 있다면 sql 튜닝을 하여 최적화 할 수 있도록 합니다.

ID 값은 위의 시나리오 Groovy 코드에서 각 부분에 해당합니다. beforeThread() 메서드 안에 record(this, "test00") 부분은 회원가입 테스트 부분만 해당됩니다.
만약 ID 값이 2 번인 곳에서 병목이 발생한다면, 해당 record(this, "test02") 로 지정된 게시글 목록 조회 부분을 쿼리 최적화를 진행해야 합니다.

시나리오 2 테스트 결과

평균 MTT : 43.5ms

시나리오 3 테스트 결과

평균 MTT : 13ms

전체 API 테스트 결과

시나리오 1 ( 52.5ms ) , 시나리오 2 ( 43.5ms ) , 시나리오 3 ( 13ms )
전체 평균 MTT : 36.3ms
최고 MTT : 182ms

모두 작성이 되었다면 웹 페이지 상단에 '성능 테스트' 버튼을 눌러 들어가면 다음과 같은 화면이 뜹니다.

에이전트 갯수, 가상 사용자, 프로세스, 쓰레드 숫자를 입력하고 실행할 스크립트를 정한 다음 우측 위에 복제 후 시작 을 눌러주면 됩니다.

설정한 시간이 끝나면 테스트를 마치며 상세 보고서를 볼 수 있습니다.
