Integration tests with REST Assured and Jetty

Question

I have a REST API running in Jetty using eclipse' jetty maven plugin; and use rest-assured for integration test. for some my IT kept failing due to connection refused. I double checked the rest-assured dependencies are up to date, so now im wondering if the jetty are really running during the IT phase. here are my code:

dependencies:

<dependency>
  <groupId>com.jayway.restassured</groupId>
  <artifactId>rest-assured</artifactId>
  <version>2.8.0</version>
  <scope>test</scope>
</dependency>
<dependency>
  <groupId>org.apache.httpcomponents</groupId>
  <artifactId>httpclient</artifactId>
  <version>4.5.1</version>
</dependency>

jetty maven plugin:

<plugin>
        <groupId>org.eclipse.jetty</groupId>
        <artifactId>jetty-maven-plugin</artifactId>
        <version>9.2.1.v20140609</version>
        <configuration>
          <httpConnector>
            <port>8103</port>
          </httpConnector>
          <stopPort>8005</stopPort>
          <stopKey>STOP</stopKey>
        </configuration>
        <executions>
          <execution>
            <id>start-jetty</id>
            <phase>pre-integration-test</phase>
            <goals>
              <goal>stop</goal>
              <goal>run-war</goal>
            </goals>
            <configuration>
              <scanIntervalSeconds>0</scanIntervalSeconds>
              <daemon>true</daemon>
            </configuration>
          </execution>
          <execution>
            <id>stop-jetty</id>
            <phase>post-integration-test</phase>
            <goals>
              <goal>stop</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
    </plugins>

IT code:

@Test
    public void testHead() throws Exception {
        //J-
        given()
            .port(PORT)
            .head(URL)   <-- /status
            .then()
            .statusCode(200);
        //J+
    }

the error message i see is:

Looks to me the jetty was not able to start at all? that's why the connect was refused? is that because the versions of jetty-maven-plugin and rest-assured are not compatible?

any solution ?? i am also getting the same error – Saurabh Verma Feb 21 '17 at 05:14 — Saurabh Verma, Feb 21 '17 at 05:14

This exception usually occurs when there is no service listening on the port that you are trying to connect to.

please check the following:

server down?
Server is not waiting/configured to get connection?
wrong port number while trying to connect?

I was struggling with integration test with rest assured using spring boot

I was not sure how to start server temp and run IT and stop when not needed.

Start server(jetty) --> run integration test -- Stop jetty ---

Thanks for ur code snippet (Jetty plugin) of pom(helpful for me and used it in my pom.xml)

I gone through link https://semaphoreci.com/community/tutorials/how-to-split-junit-tests-in-a-continuous-integration-environment and used following plugin for integration test

    <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-failsafe-plugin</artifactId>
            <version>2.19.1</version>
            <executions>
                <execution>
                    <id>integration-test</id>
                    <goals>
                        <goal>integration-test</goal>
                    </goals>
                </execution>
                <execution>
                    <id>verify</id>
                    <goals>
                        <goal>verify</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

I also faced same problem which you have faced. got solution from here testing spring boot rest application with restAssured and implemented in my code

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class MainControllerIT {

       @LocalServerPort
        private int port;

        @Before
        public void setUp() throws Exception {
        RestAssured.port = port;
        //RestAssured.baseURI="http://localhost";// optional
        }

    @Test
    public void whenRequestGet_thenOK(){
        given().when().get("/").then().statusCode(200);
    }
}

It workes!!! Now my integration test run successfully without deploying war on external server(Tomcat)
