日常开发中,如何使用了ZooKeeper,在对这部分做单元测试的时候,往往很不方便,因为实际安装一个ZooKeeper专门用来做单元测试,实在是太浪费。这种情况下,可以使用curator-test
。curator
是Netflix公司开源的一个Zookeeper
客户端,curator-test
正是其中的一员,通过它可以Mock一个本地(127.0.0.1)ZooKeeper Server用于测试,非常方便。
Maven Dependency
<dependency> <groupId>org.apache.curator</groupId> <artifactId>curator-test</artifactId> <version>2.6.0</version> <scope>test</scope> </dependency>
Getting Started
private static TestingServer server; private static CuratorFramework client; @BeforeClass public static void setUpBeforeClass() throws Exception { server = new TestingServer(2181,true); server.start(); client = CuratorFrameworkFactory.newClient("127.0.0.1",new ExponentialBackoffRetry(1000,3)); client.start(); } @AfterClass public static void tearDownAfterClass() throws IOException { server.stop(); client.close(); } @Test public void testFoobar() throws Exception { System.out.println("client: " + client); client.create().forPath("/test","test-data".getBytes()); byte[] data = client.getData().forPath("/test"); System.out.println("data: " + new String(data)); }原文链接:https://www.f2er.com/javaschema/282400.html
