spring 引導應用程序中的 Hazelcast 客戶端測試

Question

我們有一個運行 hazelcast-client 3.12.6 的 springboot 應用程序。 hazelcast 服務器不是嵌入式的，我們在外部運行它並與 hazelcast 客戶端連接。

問題是當 spring 啟動測試正在運行嵌入式 tomcat 啟動時，如果由於沒有集群運行，因此客戶端無法連接而失敗。

下面是測試 class 代碼。

@SpringBootTest(webEnvironment = WebEnvironment.RANDOM_PORT)
public class ApplicationStartTest {

  @Test
  void contextLoads() {
  }
}

我們正在使用下面提到的 bean 配置我們的 hazlecast 客戶端

  @Bean
  public ClientConfig hazelcastConfig() {
    ClientConfig config = new ClientConfig();
    String[] addresses = hazelCastEndPoints.split(",");
    ClientNetworkConfig networkConfig = config.getNetworkConfig();
    networkConfig.addAddress(addresses);
    networkConfig.setSmartRouting(false);
    networkConfig.setRedoOperation(true);
    networkConfig.setConnectionTimeout(30000);
    Timestamp timestamp = new Timestamp(System.currentTimeMillis());
    config.setInstanceName(applicationName + timestamp.toString());
//    HazelcastClient.newHazelcastClient(config);
    return config;
  }

  @Bean
  public HazelcastInstance hazelcastInstance(ClientConfig config) {
    return HazelcastClient.newHazelcastClient(config);
  }

如果您能指出如何在這種情況下運行我的測試，那將非常有幫助。

Answer 1

如果您只想要一個簡單的單元測試，那么您可以隨時模擬HazeclastInstance 。

但是，如果要創建集成（或 E2E）測試，則應先啟動 Hazelcast 服務器，然后 Hazelcast 客戶端才能連接到它。 這是一個如何使用@SpringBootTest的示例
