我尝试使用 JavaFX + Maven + TestFX（无头）我按照本教程JavaFX 无头教程启用无头模式下的测试。

主应用

public class MainApp extends Application {

@Override
public void start(Stage stage) throws Exception {
   Parent root = FXMLLoader.load(getClass().getResource("/fxml/Scene.fxml"));
   
    Scene scene = new Scene(root);
    scene.getStylesheets().add("/styles/Styles.css");
    
    stage.setAlwaysOnTop(true);
    stage.setTitle("Super Chrono");
    stage.setScene(scene);
    stage.show();

    stage.setOnCloseRequest((WindowEvent t) -> {
       try {
           sleep(1000);
       } catch (InterruptedException ex) {
           Logger.getLogger(MainApp.class.getName()).log(Level.SEVERE, null, ex);
       }
        Platform.exit();
        System.exit(0);
    });
}
/**
 * The main() method is ignored in correctly deployed JavaFX application.
 * main() serves only as fallback in case the application can not be
 * launched through deployment artifacts, e.g., in IDEs with limited FX
 * support. NetBeans ignores main().
 *
 * @param args the command line arguments
 */

public static void main(String[] args) {
    launch(args);
}

ChronoTest.java

public class ChronoTest extends ApplicationTest {
  
@BeforeClass
public static void setupHeadlessMode() {
    if(Boolean.getBoolean("headless")){
        System.setProperty("testfx.robot", "glass");
        System.setProperty("testfx.headless", "true");
        System.setProperty("prism.order", "sw");
        System.setProperty("prism.text", "t2k");
        System.setProperty("java.awt.headless", "true");                                   
    }
    //bundle = ResourceBundle.getBundle("Bundle");
}

@Before
public void beforeEachTest() throws Exception{
    FxToolkit.setupApplication(MainApp.class);
}

@Test(expected = FxRobotException.class)
public void testAffihage(){
   verifyThat("#emma", hasText("Emmanuel"));
} 

@After
public void afterEachTest() throws TimeoutException{
    FxToolkit.hideStage();
    release(new KeyCode[]{});
    release(new MouseButton[]{});
}

public <T extends Node> T find(final String query){
    return (T) lookup(query).queryAll().iterator().next();
}

}

我还添加headless=true了我的配置文件属性（NetBeans IDE）。当我尝试构建它的测试错误时，我得到了这个异常：

未能加载 Glass 工厂类

如果你有任何想法？
