Testing JavaFX application with JUnit

I've got rather simple JavaFX application:

public class Main extends Application {

@Override
public void start(Stage primaryStage) throws Exception {
    final int[] i = {0};
    FlowPane root = new FlowPane();
    root.setPadding(new Insets(40, 40, 40, 40));
    Button btn1 = new Button("Button 1");
    Button btn2 = new Button("Button 2");
    Label lbl = new Label("Output");
    Label lbl1 = new Label("Counter here");

    btn1.setOnAction(event -> { lbl.setText("Button 1 is pressed");
    lbl1.setText(""+ i[0]++);});

    btn2.setOnAction(event -> { lbl.setText("Button 2 is pressed");
        lbl1.setText(""+ i[0]++);});

    root.getChildren().addAll(lbl, btn1, btn2, lbl1);
    root.setId("root");
    primaryStage.setScene(new Scene(root, 100, 150));
    primaryStage.show();
}

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

How can I test it with JUnit framework? What aspects of the app should be tested? I just want to understand how JavaFX applications are usually subjected to test.

Well... you can perform various tests. Your choice. Logic is being tested with JUnit. If you application connects to some external system, you can perform integration tests. However, I think that your question is more related about testing JavaFX UI (functional testing) If so, you can use something like a TestFX.
