There are plenty of examples of Arquillian testing with WAR deployments, but not for other deployments such as EJB-JAR or EAR. so I created some examples. these examples were tested against Arquillian 1.1.7.Final, using WildFly 8.2.0.Final as remote container. the entire project can be obtained from GitHub.

Testing against EJB-JAR deployment

Assume we have a simple EJB in a EJB-JAR project as follows:

@Stateless
@LocalBean
public class SomeEjb {
    public String hello(String name) {
        return "Hello, " + name;
    }
}

Test class:

@RunWith(Arquillian.class)
public class EjbJarIT {
    @Deployment
    public static Archive<?> createDeploymentPackage() {
        final Archive archive = ShrinkWrap.create(JavaArchive.class).addClass(SomeEjb.class);
        return archive;
    }

    @EJB
    private SomeEjb someEjb;

    @Test
    public void test() {
        Assert.assertEquals("Hello, Kyle", someEjb.hello("Kyle"));
    }
}

The deployment will be a WAR through Arquillian’s automatic enrichment process while the method annotated as @Deployment produced JavaArchive.

Testing against EAR deployment

Assume we have a simple EAR project which depends on the preceding EJB-JAR project.

Test class:

@RunWith(Arquillian.class)
public class EarIT {

    @Deployment
    public static Archive<?> createDeploymentPackage() throws IOException {
        final JavaArchive ejbJar = ShrinkWrap.create(JavaArchive.class, "ejb-jar.jar").addClass(SomeEjb.class);

        // Embedding war package which contains the test class is needed
        // So that Arquillian can invoke test class through its servlet test runner
        final WebArchive testWar = ShrinkWrap.create(WebArchive.class, "test.war").addClass(EarIT.class);
        final EnterpriseArchive ear = ShrinkWrap.create(EnterpriseArchive.class)
                .setApplicationXML("test-application.xml")
                .addAsModule(ejbJar)
                .addAsModule(testWar);
        return ear;
    }

    @EJB
    private SomeEjb someEjb;

    @Test
    public void test() {
        Assert.assertEquals("Hello, Kyle", someEjb.hello("Kyle"));
    }
}

test-application.xml which will be embed as application.xml:

<application>
    <display-name>ear</display-name>
    <module>
        <ejb>ejb-jar.jar</ejb>
    </module>
    <module>
        <web>
            <web-uri>test.war</web-uri>
            <context-root>/test</context-root>
        </web>
    </module>
</application>

Also I have an another example that uses the EAR which Maven has produced because creating EAR with ShrinkWrap would be annoying in some complex cases. the @Deployment method will embed the test WAR into the EAR, and add a module element into existing application.xml before returning the archive to Arquillian runtime. the @Deployment method would be something like this:

...
@Deployment
public static Archive<?> createDeploymentPackage() throws IOException {
    final String testWarName = "test.war";

    final EnterpriseArchive ear = ShrinkWrap.createFromZipFile(
            EnterpriseArchive.class, new File("target/ear-1.0-SNAPSHOT.ear"));

    addTestWar(ear, EarFromZipFileIT.class, testWarName);
...
