Question

我们计划在Test Fx的帮助下测试我们的java fx场景构建器。为此下载了testfx3.1.2 jar，hamcrest-core-1.3.jar，junit.jar，guava-18.0 jar文件。

请查看下面的代码，请给我一些指示我如何启动我的gui。我的控制器类也有一些额外的方法。

public class GuiMainController extends Application implements Initializable{
 @Override
    public void start(final Stage primaryStage) throws Exception {

        primaryStage.setTitle("Plugins");
        primaryStage.setResizable(false);
        primaryStage.setScene((Scene) FXMLLoader.load(getClass().getResource(
                "/../GuiMain.fxml")));

        primaryStage.show();
    }
    /**
     * to run this class locally.
     * @param args List of Command line arguments
     */
    public static void main(final String[] args) {
        launch(args);
    }
}

我的测试课程如下。

@Category(TestFX.class)
public class GuiMainTest extends GuiTest {
    @Override
    protected Parent getRootNode() {
        Parent parent = null;
        try {
            parent = (Parent)FXMLLoader.load(
               getClass().getResource("/../GuiMain.fxml"));
            return parent;
        } catch (IOException ex) {
                   }
        return parent;
    }
    @Test
    public void setBothnamesAndCheckEnabledSearchButton() {
        try{
        ComboBox<String> listPrj = find("#lstProject");//given combobox id.
        listPrj.setValue("ABC");
        if(listPrj.getValue().equals("ABC")) {
            System.out.println("success");
        }   
        }catch(NoNodesFoundException ne){
            System.out.println("node is not available" + ne.getMessage());
        }    }
}

它给了我例外：

Answer 1

更改

primaryStage.setScene((Scene) FXMLLoader.load(getClass().getResource( "/../GuiMain.fxml")));

以

primaryStage.setScene(new Scene( FXMLLoader.load(getClass().getResource("/../GuiMain.fxml"))));
