Dropwizard: Dropwizard integration test: random read timeouts

Created on 14 Aug 2019 · 6Comments · Source: dropwizard/dropwizard

dropwizard version: 1.3.14
I have written integration test following the document
The test sometime works and randomly fails sometime with javax.ws.rs.ProcessingException: java.net.SocketTimeoutException: Read timed out

Below is my test class

public class Test {

  @ClassRule
  public static final DropwizardAppRule<MyConfigClass> RULE =
      new DropwizardAppRule<MyConfigClass>(
          MyAppcalss.class,
          ResourceHelpers.resourceFilePath("config.yml"));
  private final ObjectMapper mapper = new ObjectMapper();
  private final Client client = new JerseyClientBuilder(RULE.getEnvironment())
      .build(" REST client");

  @Before
  public void setup() {
  }

  @After
  public void tearDown() {
    client.close();
  }


  @Test
  public void loginTest() {
    ObjectNode userCredentials = mapper.createObjectNode();
    userCredentials.put("userId", "[email protected]");
    userCredentials.put("password", "test");
    Response response = client.target(
        String.format("http://localhost:%d/api/user/login", RULE.getLocalPort()))
        .request(MediaType.APPLICATION_JSON_TYPE)
        .post(Entity.entity(userCredentials.toString(), MediaType.APPLICATION_JSON_TYPE));
    Assert.assertEquals(200, response.getStatus());
  }
}

The stack trace

Can some please point out what am I doing wrong?
Or suggest some method to increase timeout?

It times out because in the DropwizardAppRule class connectTimeout is hardcoded to 1000 (1s).

protected JerseyClientBuilder clientBuilder() {
        return (new JerseyClientBuilder()).register(new JacksonBinder(this.getObjectMapper())).property("jersey.config.client.connectTimeout", 1000).property("jersey.config.client.readTimeout", 5000).property("jersey.config.client.httpUrlConnection.setMethodWorkaround", true);
    }

Instead initialise the client directly as below.

Client client = (new org.glassfish.jersey.client.JerseyClientBuilder())
                .register(new JacksonBinder(RULE.getObjectMapper()))
                .property("jersey.config.client.connectTimeout", 10000)
                .property("jersey.config.client.readTimeout", 10000)
                .property("jersey.config.client.httpUrlConnection.setMethodWorkaround", true)
                .build();

@ankurlucknowi Adding explicit time outs helped!

You can also use the JerseyClientConfiguration object directly to set the timeout.

    final JerseyClientConfiguration jerseyClientConfiguration = new JerseyClientConfiguration();
    jerseyClientConfiguration.setTimeout(Duration.minutes(1)); // wish this had a builder API
    Client client = new JerseyClientBuilder(SUPPORT.getEnvironment())
        .using(jerseyClientConfiguration)
        .build("test client");
