귀염뽀짝한 🌟유진이🌟의 JaCoCo 관련 개인 노트 공간 🧸 💓

유진이가 junit 작성 중인 Branch 이름❓ yujin_junit

Currently solving ··· 😡

1. Skipping JaCoCo when `mvn test`

-> maven surefire plugin 이랑 함께 쓸 때 argline 등 처리해주어야 하는 문제같음

[INFO] --- jacoco-maven-plugin:0.8.2:prepare-agent (default-prepare-agent) @ cse364-project ---
[INFO] argLine set to -javaagent:/Users/yujinlee/.m2/repository/org/jacoco/org.jacoco.agent/0.8.2/org.jacoco.agent-0.8.2-runtime.jar=destfile=/Users/yujinlee/IdeaProjects/CSE364_Project/target/jacoco.exec
...
[INFO] --- jacoco-maven-plugin:0.8.2:report (jacoco-report) @ cse364-project ---
[INFO] Skipping JaCoCo execution due to missing execution data file.

-> Solved ✅ reference : https://stackoverflow.com/questions/23190107/cannot-use-jacoco-jvm-args-and-surefire-jvm-args-together-in-maven

2. Test Implementation && Code Coverage > 0.9 달성

현재 유진이가 열심히 작성중

Notes 📓

pdf 에 있는 jacoco reference (https://mkyong.com/maven/maven-jacoco-code-coverage-example/)
the differences between "prepare-agent" (http://eclemma.org/jacoco/trunk/doc/prepare-agent-mojo.html) and "prepare-agent-integration" (http://eclemma.org/jacoco/trunk/doc/prepare-agent-integration-mojo.html) - are default phase and destFile location, as described in documentation
the differences between "report" (http://eclemma.org/jacoco/trunk/doc/report-mojo.html) and "report-integration" (http://eclemma.org/jacoco/trunk/doc/report-integration-mojo.html) are the same
due to those differences "prepare-agent" is intended to be used in a pair with "report", while "prepare-agent-integration" in a pair with "report-integration"
jacoco:report-integration (https://www.eclemma.org/jacoco/trunk/doc/report-integration-mojo.html)

Readme 에 추가해야 하는 내용 메모

target 디렉토리 (generated when mvn install has excuted)아래에 jacoco-report 디렉토리 생성됌.

@sirin05137 @sanghun17 너네는 이거만 보면 될 듯

JaCoCo 로 Branch coverage test 할 시

현재 target/jacoco-report 에 있는 index.html 크롬 에서 열면 아래처럼 퍼센티지 나오고
코드파일 클릭 시 test된 부분은 초록색, 안 된 부분은 빨간색으로 나옴

Junit 테스트는 이제 작성 중임.
