해결 방법

• JUnit4로 할 것인가? JUnit5로 할 것인가??  -> JUnit4로 계속

 

아래는 JUnit5로 하고 싶을 때 사용

<dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-test</artifactId>
      <scope>test</scope>
      <exclusions>		// <- 여기부터 추가
        <exclusion>
          <groupId>org.junit.vintage</groupId>
          <artifactId>junit-vintage-engine</artifactId>
        </exclusion>
      </exclusions>
    </dependency>

[Junit5] Junit4에서 Junit5으로

---

JUnit4로 계속

 

<scope>test</scope>를 제거했더니 위의 세개 의존성과 관련된 에러는 지워졌다. mockito는 없애도 똑같길래 그냥 냅둠

아까는 test 범위 지웠을 때 변화없었는데.. 왜지?(버전이 바뀌면서 용어도 바뀌었나..?)
