JUnit 4 for CDI Java-SE tests

If just plain unit testing is needed without JEE APIs it's possible to use the AbstractCdiAwareTest

@RunWith(JUnit4.class)
public class SimpleJUnitTest extends org.apache.myfaces.extensions.cdi.test.junit4.AbstractCdiAwareTest
{
    @Inject
    private Logger logger;

    @Test
    public void testLogger()
    {
        assertNotNull(this.logger);
        this.logger.info("I'm a JUnit test-case and I can use dependency injection!");
    }
}

JUnit 4 for CDI Java-EE tests

If it's required to test e.g. request scoped beans it's possible to use the AbstractServletAwareTest

@RunWith(JUnit4.class)
public class SimpleJUnitTest extends org.apache.myfaces.extensions.cdi.test.junit4.AbstractServletAwareTest
{
    @Inject
    private RequestScopedBean requestScopedBean;

    @Test
    public void testLogger()
    {
        assertNotNull(this.requestScopedBean.getValue());
    }
}

If it's required to test e.g. grouped conversation scoped beans it's possible to use the AbstractServletAwareTest

@RunWith(JUnit4.class)
public class SimpleJUnitTest extends org.apache.myfaces.extensions.cdi.test.junit4.AbstractJsfAwareTest
{
    @Inject
    private ViewAccessScopedBean viewAccessScopedBean;

    @Test
    public void testLogger()
    {
        assertNotNull(this.viewAccessScopedBean.getValue());
    }
}

Needed modules and dependencies

Because the unit-test modules will never be needed in production builds, you have to add the CODI-test modules manually, even if you are using one of the all-in-one packages. You'll need at least the myfaces-extcdi-junit-support-module for general JUnit support. And depending on your needs, you'll also need the myfaces-extcdi-owb-support-module and myfaces-extcdi-jsf-support-module. Don't forget to also include the needed (test)modules of the CDI implementation. In case of OWB, you'll need cditest and cditest-owb from the org.apache.openwebbeans.test group. For convenience, here's a pom-snippet to pick the needed dependencies from:
