    Artist a1 = context.newObject(Artist.class);
    a1.setValidationDelegate(delegate);
    a1.setArtistName("a1");
    // add another artist to ensure that modifying context works when more than one
    // object is committed
    Artist a2 = context.newObject(Artist.class);
    a2.setValidationDelegate(delegate);
    a2.setArtistName("a2");
    context.commitChanges();
    assertEquals(2, context.performQuery(new SelectQuery(Painting.class)).size());
