MY code:
@RunWith(FeaturesRunner.class)
@Features(CoreFeature.class)
@RepositoryConfig(type=BackendType.H2, user = "Administrator", init=DefaultRepositoryInit.class)
public class MyTest {
    @Inject FeaturesRunner runner;
    @Inject CoreSession session;

  @Test public void doMvelTest() throws ClientException {
      assertNotNull(session);
      assertNotNull(session.getDocument(new PathRef("/default-domain")));

      //test1
      DocumentModel ws3 = session.createDocumentModel("Workspace");
      //ws3.setPropertyValue("dc:title", "WS3");
      String[] fakeContributors = { "Administrator" };
      ws3.setPropertyValue("dc:contributors", fakeContributors);
      ws3.setPropertyValue("dc:creator", fakeContributors[0]);
      ws3.setPropertyValue("dc:creator", "Administrator");

your help would be greatly appreciated
