我们计划在test-fx的帮助下测试我们的javafx场景生成器。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,并给我一些如何启动gui的提示。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);
}
}
我的测试课在下面。
@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());
} }
}
它给了我一个例外:

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