Arquillian over Wildfly DeploymentException: WELD-001408: Unsatisfied dependencies

I've a very simple test:

@RunWith(Arquillian.class)
public class SimpleTest
{

    @Inject private SingleEntity singleEntity;

    @Deployment
    public static JavaArchive createDeployment()
    {   
        return ShrinkWrap.create(JavaArchive.class)
            .addClass(SingleEntity.class)
            .addAsManifestResource(EmptyAsset.INSTANCE, "beans.xml");
    }

    @Test
    public void categorize()
    {
        assertNotNull(this.singleEntity);
    }
}

I only want to inject a object of type SingleEntity. SingleEntity is a single POJO:

public class SingleEntity
{
    private String id;
    private String description;

    public SingleEntity(String id, String description) {
        super();
        this.id = id;
        this.description = description;
    }

    //getters & setters
}

After, that I perform gradle test. I've configured tests in order for Arquillian to perform them in a Wildfly embedded instance:

<arquillian xmlns="http://ift.tt/Rj5rcy"  
    xmlns:xsi="http://ift.tt/ra1lAU"  
    xsi:schemaLocation="http://ift.tt/Rj5rcy http://ift.tt/U5TLp1">  

    <container qualifier="jboss" default="true">  
        <configuration>  
        <!-- Supported property names: [managementPort, username, managementAddress, bundlePath, managementProtocol,   
                    cleanServerBaseDir, jbossHome, password, modulePath] -->  
            <property name="jbossHome">C:\servers\wildfly-Test-8.2.0.Final</property>
            <property name="modulePath">C:\servers\wildfly-Test-8.2.0.Final\modules\</property>
            <!-- <property name="managementPort">8888</property> -->  
        </configuration>  
    </container>  
</arquillian>  

It's very straightforward, however, I receive a exception telling me SingleEntity cann't be resolved:

Caused by: org.jboss.weld.exceptions.DeploymentException: WELD-001408: Unsatisfied dependencies for type SingleEntity with qualifiers @Default at injection point [BackedAnnotatedField] @Inject private com.jeusdi.arquillian.SimpleTest.singleEntity at com.jeusdi.arquillian.SimpleTest.singleEntity(SimpleTest.java:0)

Any ideas? Thanks for all
