+description: 테스트 코드를 작성하거나 수정할 때 이 프로젝트의 테스트 컨벤션과 패턴을 참고합니다
+---
+
+# 테스트 코드 작성 가이드
+
+## 테스트 기본 설정
+
+모든 통합 테스트는 `@TestContainerSpringBootTest` 어노테이션을 사용합니다.
+
+```java
+@TestContainerSpringBootTest
+@DisplayName("채팅 서비스 테스트")
+class ChatServiceTest {
+    // 테스트 코드
+}
+```
+
+**제공 기능:**
+- MySQL, Redis 자동 실행
+- Spring Boot 컨텍스트 로드
+- 테스트 후 자동 DB 초기화
+- JUnit 5 기반
+
+## Fixture 패턴
+
+테스트 데이터는 Fixture로 생성합니다 (FixtureBuilder + Fixture 패턴).
+
+**위치:** `src/test/java/com/example/solidconnection/[domain]/fixture/`
+
+```
+fixture/
+├── [Entity]FixtureBuilder.java    # Builder 패턴 구현
+└── [Entity]Fixture.java            # 편의 메서드 제공
+```
+
+### 예제: ChatRoomFixtureBuilder
+
+```java
+@TestComponent
+@RequiredArgsConstructor
+public class ChatRoomFixtureBuilder {
+
+    private final ChatRoomRepository chatRoomRepository;
+
+    private boolean isGroup;
+    private Long mentoringId;
+
+    public ChatRoomFixtureBuilder chatRoom() {
+        return new ChatRoomFixtureBuilder(chatRoomRepository);
+    }
+
+    public ChatRoomFixtureBuilder isGroup(boolean isGroup) {
+        this.isGroup = isGroup;
+        return this;
+    }
+
+    public ChatRoomFixtureBuilder mentoringId(long mentoringId) {
+        this.mentoringId = mentoringId;
+        return this;
+    }
+
+    public ChatRoom create() {
+        ChatRoom chatRoom = new ChatRoom(mentoringId, isGroup);
+        return chatRoomRepository.save(chatRoom);  // DB 저장
+    }
+}
+```
+
+### 예제: ChatRoomFixture
+
+```java
+@TestComponent
+@RequiredArgsConstructor
+public class ChatRoomFixture {
+
+    private final ChatRoomFixtureBuilder chatRoomFixtureBuilder;
+
+    // 편의 메서드: 기본값으로 생성
+    public ChatRoom 채팅방(boolean isGroup) {
+        return chatRoomFixtureBuilder.chatRoom()
+                .isGroup(isGroup)
+                .create();
+    }
+
+    public ChatRoom 멘토링_채팅방(long mentoringId) {
+        return chatRoomFixtureBuilder.chatRoom()
+                .mentoringId(mentoringId)
+                .isGroup(false)
+                .create();
+    }
+}
+```
+
+**편의 메서드 작성 팁:**
+
+- 한국어 메서드명 사용 (가독성)
+- 자주 사용되는 기본값 조합만 제공
+- Builder를 조합하여 필요한 데이터 설정
+
+### 테스트에서 사용
+
+```java
+@TestContainerSpringBootTest
+class ChatServiceTest {
+
+    @Autowired
+    private ChatRoomFixture chatRoomFixture;
+
+    @Test
+    void 채팅방을_생성할_수_있다() {
+        // 편의 메서드 사용
+        ChatRoom room = chatRoomFixture.채팅방(false);
+
+        // Builder 직접 사용
+        ChatRoom customRoom = chatRoomFixture.chatRoomFixtureBuilder.chatRoom()
+                .isGroup(true)
+                .mentoringId(100L)
+                .create();
+    }
+}
+```
+
+## 테스트 네이밍 컨벤션
+
+### 테스트 메서드 네이밍 규칙
+
+테스트 메서드명은 **한국어로 명확하게** 작성하며, 다음 패턴을 따릅니다:
+
+#### 1. 정상 동작 테스트
+
+```java
+// 패턴: 어떤_것을_하면_어떤_결과가_나온다
+@Test
+void 채팅방이_없으면_빈_목록을_반환한다() { ... }
+
+@Test
+void 최신_메시지_순으로_정렬되어_조회한다() { ... }
+
+@Test
+void 참여자는_메시지를_전송할_수_있다() { ... }
+
+@Test
+void 페이징이_정상_작동한다() { ... }
+```
+
+#### 2. 예외 테스트
+
+```java
+// 패턴: 어떤_것을_하면_예외_응답을_반환한다
+@Test
+void 참여하지_않은_채팅방에_접근하면_예외_응답을_반환한다() { ... }
+
+@Test
+void 존재하지_않는_사용자로_메시지를_전송하면_예외_응답을_반환한다() { ... }
+
+@Test
+void 권한이_없으면_예외_응답을_반환한다() { ... }
+
+@Test
+void 필수_파라미터가_없으면_예외_응답을_반환한다() { ... }
+```
+
+## BDD 테스트 작성
+
+테스트는 Given-When-Then 구조로 작성합니다.
+
+```java
+@Test
+@DisplayName("최신 메시지순으로 채팅방 목록을 조회한다")
+void 최신_메시지_순으로_조회한다() {
+    // Given: 테스트 사전 조건
+    SiteUser user = siteUserFixture.사용자();
+    ChatRoom room1 = chatRoomFixture.채팅방(false);
+    ChatRoom room2 = chatRoomFixture.채팅방(false);
+    chatMessageFixture.메시지("오래된 메시지", user.getId(), room1);
+    chatMessageFixture.메시지("최신 메시지", user.getId(), room2);
+
+    // When: 실제 동작
+    ChatRoomListResponse response = chatService.getChatRooms(user.getId());
+
+    // Then: 결과 검증
+    assertAll(
+        () -> assertThat(response.chatRooms()).hasSize(2),
+        () -> assertThat(response.chatRooms().get(0).id()).isEqualTo(room2.getId())
+    );
+}
+```
+
+## 테스트 그룹화 (@Nested)
+
+기능별로 테스트를 그룹화합니다.
+
+```java
+@TestContainerSpringBootTest
+class ChatServiceTest {
+
+    @Nested
+    @DisplayName("채팅방 목록 조회")
+    class 채팅방_목록을_조회한다 {
+
+        @Test
+        void 빈_목록을_반환한다() { ... }
+
+        @Test
+        void 최신_메시지_순으로_조회한다() { ... }
+    }
+
+    @Nested
+    @DisplayName("채팅 메시지 전송")
+    class 채팅_메시지를_전송한다 {
+
+        @BeforeEach
+        void setUp() {
+            // 이 그룹에만 적용되는 초기 설정
+        }
+
+        @Test
+        void 참여자는_메시지를_전송할_수_있다() { ... }
+    }
+}
+```
+
+## 자주 사용하는 Assertion
+
+```java
+// 기본 검증
+assertThat(value).isEqualTo(expected);
+assertThat(value).isNotNull();
+
+// 컬렉션
+assertThat(list).hasSize(3);
+assertThat(list).isEmpty();
+assertThat(list).contains(item);
+
+// 예외 검증
+assertThatCode(() -> method())
+    .isInstanceOf(CustomException.class)
+    .hasMessage("error message");
+
+// 복수 검증
+assertAll(
+    () -> assertThat(a).isEqualTo(1),
+    () -> assertThat(b).isEqualTo(2)
+);
+```
