zookeeper springboot怎么进行单元测试

在Spring Boot项目中，我们可以使用JUnit和Mockito等工具进行单元测试。以下是一个简单的示例，展示了如何使用Zookeeper和Spring Boot进行单元测试：

1. 首先，确保你的项目中已经添加了Zookeeper的依赖。在pom.xml文件中添加以下依赖：

    org.apache.zookeeper
    zookeeper
    3.7.0

2. 创建一个Zookeeper配置类：

@Configuration
public class ZookeeperConfig {

    @Bean
    public CuratorFramework curatorFramework() {
        CuratorFramework client = CuratorFrameworkFactory.builder()
                .connect("localhost:2181", new ExponentialBackoffRetry(1000, 3))
                .build();
        client.start();
        return client;
    }
}

3. 创建一个使用Zookeeper的服务类：

@Service
public class ZookeeperService {

    @Autowired
    private CuratorFramework curatorFramework;

    public String createNode(String path) throws Exception {
        return curatorFramework.create().creatingParentsIfNeeded().forPath(path);
    }

    public boolean isNodeExists(String path) throws Exception {
        return curatorFramework.checkExists().forPath(path) != null;
    }
}

4. 创建一个Zookeeper服务的单元测试类：

@RunWith(SpringRunner.class)
public class ZookeeperServiceTest {

    @Autowired
    private ZookeeperService zookeeperService;

    @MockBean
    private CuratorFramework curatorFramework;

    @Before
    public void setUp() {
        MockitoAnnotations.initMocks(this);
    }

    @Test
    public void testCreateNode() throws Exception {
        String path = "/testNode";
        zookeeperService.createNode(path);
        Mockito.verify(curatorFramework, Mockito.times(1)).create().creatingParentsIfNeeded().forPath(path);
    }

    @Test
    public void testIsNodeExists() throws Exception {
        String path = "/testNode";
        Mockito.when(curatorFramework.checkExists().forPath(path)).thenReturn(new Stat());
        boolean result = zookeeperService.isNodeExists(path);
        assertTrue(result);
        Mockito.verify(curatorFramework, Mockito.times(1)).checkExists().forPath(path);
    }
}

在这个示例中，我们使用了@RunWith(SpringRunner.class)来启用Spring Boot的测试支持，@MockBean来创建一个Zookeeper的模拟对象，@Before注解来初始化Mockito注解。在测试方法中，我们使用Mockito.verify()来验证Zookeeper服务类中的方法是否被正确调用。
