+# Spring Boot 单元测试学习示例（基于JDBC）
+
+这是一个完整的Spring Boot单元测试学习项目，演示了如何使用JUnit 5和Mockito编写高质量的单元测试。
+项目使用纯JDBC方式（非JPA），更贴近传统的数据库操作方式。
+

+    └── service/         # 单元测试类
+```
+
+## 技术栈
+
+- **Spring Boot 3.1.5**
+- **Java 17**
+- **JUnit 5** - 测试框架
+- **Mockito** - Mock框架
+- **AssertJ** - 断言库
+- **Maven** - 构建工具
+
+## 核心功能
+
+UserService提供以下业务功能：
+1. **用户注册** (`registerUser`)
+2. **用户登录** (`loginUser`)
+3. **修改密码** (`changePassword`)
+4. **删除用户** (`deleteUser`)
+5. **获取用户信息** (`getUserById`)
+
+## 测试覆盖
+
+单元测试覆盖了以下场景：
+
+### 正常场景测试
+- 成功注册新用户
+- 成功登录
+- 成功修改密码
+- 成功删除用户
+- 成功获取用户信息
+
+### 异常场景测试
+- 用户名/邮箱已存在
+- 用户不存在
+- 密码错误
+- 输入验证失败
+- 空值处理
+
+### 边界条件测试
+- 用户名长度边界（3-20字符）
+- 密码长度边界（6-20字符）
+- 特殊字符处理
+
+### Mock验证测试
+- 方法调用次数验证
+- 方法调用顺序验证
+- 参数验证
+
+## 如何运行
+
+### 1. 克隆项目
+```bash
+git clone <repository-url>
+cd springboot-test
+```
+
+### 2. 运行所有测试
+```bash
+mvn test
+```
+
+### 3. 运行特定测试
+```bash
+# 运行特定测试类
+mvn test -Dtest=UserServiceTest
+
+# 运行特定测试方法
+mvn test -Dtest=UserServiceTest#registerUser_Success
+```
+
+### 4. 生成测试报告
+```bash
+mvn surefire-report:report
+```
+
+## 关键学习点
+
+### 1. 测试注解
+- `@ExtendWith(MockitoExtension.class)` - 启用Mockito
+- `@Mock` - 创建模拟对象
+- `@InjectMocks` - 注入依赖
+- `@Nested` - 组织测试
+- `@DisplayName` - 测试描述
+
+### 2. 测试模式
+```java
+@Test
+void testMethod() {
+    // Given - 准备测试数据
+    // When - 执行测试
+    // Then - 验证结果
+}
+```
+
+### 3. Mock使用
+```java
+// 定义行为
+when(repository.findById(1L)).thenReturn(Optional.of(user));
+
+// 验证调用
+verify(repository).save(any(User.class));
+
+// 捕获参数
+ArgumentCaptor<User> captor = ArgumentCaptor.forClass(User.class);
+verify(repository).save(captor.capture());
+```
+
+### 4. 断言示例
+```java
+// 基本断言
+assertThat(result).isNotNull();
+assertThat(result.getUsername()).isEqualTo("testuser");
+
+// 异常断言
+assertThatThrownBy(() -> service.method())
+    .isInstanceOf(ValidationException.class)
+    .hasMessage("Error message");
+```
+
+## 最佳实践
+
+1. **单一职责**: 每个测试只验证一个功能点
+2. **独立性**: 测试之间相互独立
+3. **可读性**: 使用描述性的测试名称
+4. **完整性**: 覆盖正常和异常场景
+5. **可维护性**: 使用常量避免硬编码
+
+## 扩展学习
+
+- 集成测试 (`@SpringBootTest`)
+- 数据库测试 (`@DataJpaTest`)
+- Web层测试 (`@WebMvcTest`)
+- 测试容器 (Testcontainers)
+- 性能测试 (JMH)
+

+
+## 关键知识点总结
+
+### 1. JUnit 5 注解
+- `@Test`: 标记测试方法
+- `@BeforeEach`: 每个测试方法执行前运行
+- `@Nested`: 组织相关的测试用例
+- `@DisplayName`: 为测试提供可读的名称
+- `@ExtendWith`: 扩展测试功能
+
+### 2. Mockito 使用
+- `@Mock`: 创建模拟对象
+- `@InjectMocks`: 注入模拟对象到被测试类
+- `when().thenReturn()`: 定义模拟行为
+- `verify()`: 验证方法调用
+- `ArgumentCaptor`: 捕获方法参数
+
+### 3. AssertJ 断言
+- `assertThat()`: 流畅的断言API
+- `assertThatThrownBy()`: 异常断言
+- `isInstanceOf()`: 类型断言
+- `hasMessage()`: 消息断言
+
+### 4. 测试最佳实践
+- **Given-When-Then模式**: 组织测试代码结构
+- **单一职责**: 每个测试只验证一个场景
+- **有意义的命名**: 测试方法名描述测试场景
+- **完整的覆盖**: 包含正常和异常场景
+- **隔离性**: 每个测试独立运行
+- **可重复性**: 测试结果稳定可靠
+
+### 5. Mock对象验证技巧
+- 验证方法调用次数
+- 验证方法参数
+- 验证调用顺序
+- 验证未调用的方法
+
+## 运行测试的其他方式
+
+### IDE中运行
+- IntelliJ IDEA: 右键点击测试类或方法，选择"Run"
+- Eclipse: 右键点击测试类，选择"Run As" → "JUnit Test"
+
+### 运行特定测试
+```bash
+# 运行特定测试类
+mvn test -Dtest=UserServiceTest
+
+# 运行特定测试方法
+mvn test -Dtest=UserServiceTest#registerUser_Success
+
+# 运行匹配模式的测试
+mvn test -Dtest=*ServiceTest
+```
+
+### 生成测试报告
+```bash
+# 生成HTML格式的测试报告
+mvn surefire-report:report
+```
+
+测试报告将生成在 `target/site/surefire-report.html`
