JUnit

메소드 테스트

 

src/test/java에 가서 class 생성

package com.bit;

import com.bit.domain.Board;
import com.bit.persistence.BoardRepository;
//RunWith(SpringRunner.class) 낮은 버전에서는 이거 사용 했었음
@ExtendWith(SpringExtension.class)
@SpringBootTest

public class BoardRepositoryTests {
	@Autowired
	BoardRepository repo;
	
	@Test
	public void testCreate() {
		System.out.println("테이블 생성");
	}

			Board board = new Board();
			board.setTitle("제목 :"+i);
			board.setContent("내용 :"+i+"채우기");
			board.setWriter("user0 :"+i%10);

		}
	}
	
	@Test
	public void testByTitle() {

			System.out.println(board);
		}
		
		for(Board board:results) {
			System.out.println(board);
		}
		
		results.forEach(board->System.out.println(board)); //람다 1
		
		results.forEach(System.out::println); // 람다 2
	}
	
	@Test
	public void testByWriter() {
		repo.findByWriter("user0 :0").forEach(System.out::println);;
	}
	
	@Test
	public void update200() {

			Iterable<Board> iter = repo.findAll();
			iter.forEach(board->board.setContent("1"));
			repo.saveAll(iter);
//			repo.save(board);
		}
	}
	
	@Test
	public void testContent() {
		repo.findByContent("내용...0 채우기").
		forEach(board->System.out.println(board));
	}
	
	@Test
	public void testByTitleContaining() {
		repo.findByTitleContaining("7").
		forEach(board->System.out.println(board));
	}
	
	@Test
	public void testByContentEndingWith() {
		repo.findByContentEndingWith("9 채우기").
		forEach(board->System.out.println(board));

	}
	
	@Test
	public void testByWriterEndingWith() {
		repo.findByWriterEndingWith("7").
		forEach(board->System.out.println(board));

	}
	
	@Test
	public void testByTitleStartingWith() {
		repo.findByTitleStartingWith("제목 :2").
		forEach(board->System.out.println(board));

	}

}

@Test 꼭 붙여야함

 

Run configuration 에 가면 Test method에서 테스트할 메소드 선택 가능
