NameTesting Frameworks SupportedDescription
Camel CDI Test
  • JUnit 4

Available as of Camel 2.17

The Camel CDI test module (camel-test-cdi) provides a JUnit runner that bootstraps a test environment using CDI so that you don't have to be familiar with any CDI testing frameworks and can concentrate on the testing logic of your Camel CDI applications.

Arquillian
  • JUnit 4
  • TestNG 5
Arquillian is a testing platform that handles all the plumbing of in-container testing with support for a wide range a of target containers. Arquillian can be configured to run your test classes in embedded (in JVM CDI), managed (a real Web server or Java EE application server instance started in a separate process) or remote (the lifecycle of the container isn't managed by Arquillian) modes. You have to create the System Under Test (SUT) in your test classes using ShrinkWrap Descriptors. The benefit is that you have a very fine-grained control over the application configuration that you want to test. The downside is more code and more complex classpath / class loading structure.
PAX Exam
  • JUnit 4
  • TestNG 6
PAX Exam lets you test your Camel applications in OSGi, Java EE or standalone CDI containers with the ability to finely configured your System Under Test (SUT), Similarly to Arquillian. You can use it to test your Camel CDI applications that target OSGi environments like Karaf with PAX CDI, but you can use it as well to test your Camel CDI applications in standalone CDI containers, Web containers and Java EE containers.

Camel CDI Test

With this approach, your test classes use the JUnit runner provided in Camel CDI test. This runner manages the lifecycle of a standalone CDI container and automatically assemble and deploy the System Under Test (SUT) based on the classpath into the container.

...

Code Block
languagejava
@RunWith(Arquillian.class)
public class CamelCdiWebTest {

    @Deployment
    public static Archive<?> createTestArchive() {
        return ShrinkWrap.create(WebArchive.class)
            .addClass(Application.class)
            .addAsWebInfResource(EmptyAsset.INSTANCE, ArchivePaths.create("beans.xml"))
            .setWebXML(Paths.get("src/main/webapp/WEB-INF/web.xml").toFile());
    }

    @Test
    @RunAsClient
    public void test(@ArquillianResource URL url) throws Exception {
        assertThat(IOHelper.loadText(new URL(url, "camel/rest/hello").openStream()),
            is(equalTo("Hello World!\n")));
    }
}

PAX Exam

If your target OSGi as runtime environment for your Camel CDI applications, you can use PAX Exam to automate the deployment of your tests into an OSGi container, for example into Karaf, e.g.:

Code Block
languagejava
@RunWith(PaxExam.class)
@ExamReactorStrategy(PerClass.class)
public class PaxCdiOsgiTest {

    @Configuration
    public Option[] config() throws IOException {
        return options(
            // Karaf configuration
            karafDistributionConfiguration()
                .frameworkUrl(
                    maven()
                       .groupId("org.apache.karaf")
                       .artifactId("apache-karaf")
                       .versionAsInProject()
                       .type("zip"))
                .name("Apache Karaf")
                .unpackDirectory(new File("target/paxexam/unpack/")),
            // PAX CDI Weld
            features(
                maven()
                    .groupId("org.ops4j.pax.cdi")
                    .artifactId("pax-cdi-features")
                    .type("xml")
                    .classifier("features")
                    .versionAsInProject(),
                "pax-cdi-weld"),
            // Karaf Camel commands
            mavenBundle()
                .groupId("your.application.groupId")
                .artifactId("your.application.artifactId")
                .versionAsInProject()
        );
    }
 
    @Inject
    private CamelContext context;

    @Test
    public void testContextStatus() {
        assertThat("Camel context status is incorrect!",
            context.getStatus(), equalTo(ServiceStatus.Started));
    }
}

You can see the tests in the camel-example-cdi-osgi example for a complete working example of testing a Camel CDI application deployed in an OSGi container using PAX Exam.
