Mock을 활용한 테스트
@Repository
public class BookRepository {
public Book save(Book book) {
return null;
}
}
@Service
public class Book Service {
private BookRepository bookRepository;
public BookService(BookRepository bookRepository) {
this.bookRepository = bookRepository;
}
}
위와 같이 의존성이 있는 객체에 대한 구현이 되지 않았을 때 단위 테스트를 진행하는 방법은 아래와 같다.
@RunWith(SpringRunner.class)
public class BookServiceTest {
@Mock
BookRepository bookRepository;
@Test
public void save() {
Book book = new Book();
//bookRepository.save(book)를 호출할 때 book을 리턴해줌
when(bookRepository.save(book)).thenReturn(book);
BookService bookService = new BookService(bookRepository);
Book result = bookService.save(book);
assertThat(Book.getCreated()).isNotNull();
assertThat(book.getBookStatus()).isEqualTo(BookStatus.DRAFT);
assertThat(result).isNotNull();
}
}
