Testing is a crucial part of any development or integration work. In case you're using the Camel CDI integration for your applications, you have a number of options to ease testing.

You can use CDI for IoC and the Camel testing endpoints like DataSet, Mock, Test and testing API like AdviceWith and NotifyBuilder to create sophisticated integration/unit tests that are easy to run and debug inside your IDE.

There are two supported approaches for testing with CDI in Camel:

NameTesting Frameworks SupportedDescription
Camel CDI Test
  • JUnit 4

The Camel CDI test module ({{camel-test-cdi}}) comes with a JUnit that you can use to delegate all

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 target runtime

Camel CDI Test

With this approach, your test classes use the JUnit test 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.

It deploys the test class as a CDI bean so that dependency injection and any CDI features is available within the test class.

Maven users will need to add the following dependency to their pom.xml for this component:

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-test-cdi</artifactId>
    <scope>test</test>
    <version>x.x.x</version>
    <!-- use the same version as your Camel core version -->
</dependency>

Here is a simple unit test using the CamelCdiRunner:

 

@RunWith(CamelCdiRunner.class)
public class CamelCdiRunnerTest {

    @Inject
    CamelContext context;

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



Arquillian


@RunWith(Arquillian.class)
public class CamelCdiJavaSeTest {

    @Deployment
    public static Archive deployment() {
        return ShrinkWrap.create(JavaArchive.class)
            // Camel CDI
            .addPackage(CdiCamelExtension.class.getPackage())
            // Test classes
            .addPackage(Application.class.getPackage())
            // Bean archive deployment descriptor
            .addAsManifestResource(EmptyAsset.INSTANCE, "beans.xml");
    }
 
    @Inject
    CamelContext context;

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