Jetty 9.3.4 not working with integration tests

问题


I'm running integration tests using jersey, jetty 9.x, jetty-maven-plugin and the maven-failsafe-plugin.

Integration tests worked well with jetty 9.2.0.M0 specified in jetty-maven-plugin. When using version 9.3.4.RC1, jetty starts, but no integration tests are run.

Here's my pom.xml:

</web-app>

Thats a minimal web-service example:
App.java:

package my.example.jetty_integration_test;


import org.glassfish.jersey.server.ResourceConfig;

public class App extends ResourceConfig {
    /**
     * Register JAX-RS application components.
     */
    public App() {
        register(WebService.class);
    }
}

WebService.java:

package my.example.jetty_integration_test;


import ...

// Browse to http://localhost:8081/rest/webservice

@Path("webservice")
public class WebService {


    @GET
    @Produces(MediaType.TEXT_PLAIN)
    public String getIt() {
        return "Got it!";
    }
}

And a minimal integration test that shows the problem:
AppITCase.java

package my.example.jetty_integration_test;

import ...

/**
 * Unit test for simple App.
 */
public class AppITCase {
    CloseableHttpClient httpClient;

    @Before
    public void setUp() {
        httpClient = HttpClients.createDefault();
    }

    @After
    public void tearDown() {
        try {
            httpClient.close();
        } catch (IOException e) {
            throw new RuntimeException(e);
        }
    }

    @Test
    public void canCallWebService() {
        // Given.
        HttpGet httpGet = new HttpGet("http://localhost:8081/rest/webservice");
        // When.
        CloseableHttpResponse httpResponse = tryHttpRequest(httpGet);
        String text = tryReadHttpBody(httpResponse);
        // Then.
        assertEquals("Got it!", text.trim());

    }

    private CloseableHttpResponse tryHttpRequest(HttpUriRequest httpRequest) {
        CloseableHttpResponse httpResponse = null;
        try {
            httpResponse = httpClient.execute(httpRequest);
        } catch(Exception e) {
            throw new RuntimeException(e);
        }
        return httpResponse;
    }

    private String tryReadHttpBody(HttpResponse httpResponse){
        try {
            InputStream inputStream = httpResponse.getEntity().getContent();
            byte[] bytes = new byte[64];
            inputStream.read(bytes, 0, bytes.length);
            return new String(bytes);
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }
}

When switching between the two jetty versions in the pom.xml, mvn clean verify will work or it will not run any IT case... How can I run integration tests using the newer jetty version?

Edit: After jetty started, failsafe does not make any output to the console (It does as usual for jetty 9.2.0.M0).
Console output from maven clean verify with jetty 9.3.4.RC1:

回答1:


The use of jetty-maven-plugin:run means you are running your <packaging>war</packaging> project with Jetty. Your project is sitting deployed and ready for you to hit it with a Browser (or really, anything not inside of the Maven process).

When you are done you simple Ctrl+C to stop that Jetty instance.

Perhaps you are thinking of jetty-maven-plugin:start (and its associated jetty-maven-plugin:stop) which is meant to start Jetty and not block waiting for the Jetty process to be stopped (or exited)

See https://www.eclipse.org/jetty/documentation/current/jetty-maven-plugin.html#jetty-start-goal
