Thanks Emmanuel, it's what I did temporary and it's work as well.

I finally get it working with an Arquillian extension, here is the extension code  :

public class DeployForEachTestsExtension implements LoadableExtension {

   @Override
   public void register(ExtensionBuilder builder) {
      builder.observer(Handler.class);
   }

   public static class Handler {

        public void executeOnJUnitBefore(@Observes Before event, Deployer deployer, TestClass testClass) {
            Deployment deployment = findRequiredAnnotation(testClass, Deployment.class);
            if (hasToManage(testClass, deployment)) {
                deployer.deploy(deployment.name());
            }
        }

        public void executeOnJUnitAfter(@Observes After event, Deployer deployer, TestClass testClass) {
            Deployment deployment = findRequiredAnnotation(testClass, Deployment.class);
            if (hasToManage(testClass, deployment)) {
                deployer.undeploy(deployment.name());
            }
        }

        private boolean hasToManage(TestClass testClass, Deployment deployment) {
            return !deployment.managed()
                && findAnnotation(testClass, DeployForEachTests.class) != null;
        }

        private <T extends Annotation> T findRequiredAnnotation(TestClass testClass, Class<T> annotation) {
            Method deploymentMethod = findAnnotation(testClass, annotation);
            if (deploymentMethod != null) {
                return deploymentMethod.getAnnotation(annotation);
            }
            throw new IllegalStateException(annotation.getName() + " not found in given test class");
        }

        private <T extends Annotation> Method findAnnotation(TestClass testClass, Class<T> annotation) {
            return testClass.getMethod(annotation);
        }
   }
}

And I use it like that (I also created an annotation @DeployForEachTests):

    @DeployForEachTests
    @Deployment(managed=false, name=ARCHIVE) 
    public static WebArchive createDeployment() {
        return ObmSyncArchiveUtils
                .buildWebArchive(CalendarBindingImplIntegrationTestModule.class)
                .addAsResource("sql/org/obm/sync/calendar/h2.sql", H2GuiceServletContextListener.INITIAL_DB_SCRIPT)
                .addClasses(CalendarBindingImplIntegrationTestModule.class);
    }

Thanks to Emmanuel and Aslak for your help !

Hello Tommy, as I explained at https://community.jboss.org/message/830724#830724

Briefly it's to clean the whole webapp state, not only the database, between two tests !
