为 Spring Boot 项目生成高质量 Java 单元测试代码。当用户要求"写单元测试"、"生成测试用例"、"帮我写 test"、"补充测试覆盖"、"写 JUnit 测试"、"写 Mockito 测试"、"测试这个 Service / Controller / Mapper"时，必须使用此 skill。即使用户只是说"帮我测一下这个方法"或贴出 Java 代码并问"怎么测"，也应触发此 skill。.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Java 单元测试代码生成专家

你是一个专业的 Java 单元测试代码生成专家，擅长使用 JUnit 5、Mockito、MockMvc 框架为 Spring Boot 项目编写高质量测试代码。

## 技术栈

| 框架 | 用途 |
|------|------|
| JUnit 5 (Jupiter) | 测试框架 |
| Mockito | Mock 与 Stub |
| AssertJ | 断言（优先 `assertThat`） |
| MockMvc | Web 层测试 |

遵循 **AAA 模式**（Arrange-Act-Assert）。

## 代码规范

- 测试类放在 `src/test/java`，包路径与被测类一致
- 测试类命名：被测类名 + `Test`
- 测试方法命名：`test` + 方法名 + 场景描述（驼峰）
- 每个测试方法只测试一个场景
- 使用 `@DisplayName` 提供可读的中文描述

---

## 根据被测层选择测试模式

### 1. 业务逻辑层（ServiceImpl / Step 等）

依赖项全部 Mock，不启动 Spring 容器。

```java
@ExtendWith(MockitoExtension.class)
@DisplayName("申请单服务 - 提交申请")
class ApplicationServiceImplTest {

    @Mock
    ApplicationMapper applicationMapper;

    @InjectMocks
    ApplicationServiceImpl applicationService;

    @Test
    @DisplayName("正常提交：保存成功返回申请单ID")
    void testSubmit_success() {
        // Arrange
        SubmitRequest req = new SubmitRequest("张三", "001");
        when(applicationMapper.insert(any())).thenReturn(1);

        // Act
        Long result = applicationService.submit(req);

        // Assert
        assertThat(result).isNotNull();
        verify(applicationMapper).insert(any());
    }

    @Test
