cd javaee7-samples/jaxrs/beanvalidation/Now we are ready to start testing. You can run all the tests in this sample by executing:mvn testOr you can run individual tests by executing one of the following:mvn test -Dtest=MyResourceTest@Deployment(testable = false)
public static WebArchive createDeployment() {
    return ShrinkWrap.create(WebArchive.class)
            .addClasses(MyApplication.class, MyResource.class);
