FEST：在执行任何操作之前等待GUI加载 [英] FEST: Wait for the GUI to load before doing anything

问题描述

    @Before public void setUp() {
        Robot robot = BasicRobot.robotWithCurrentAwtHierarchy();
        ApplicationLauncher.application("myApp").start(); 

        Pause.pause(5, TimeUnit.SECONDS); 
        frame = WindowFinder.findFrame("frame0").using(robot);

        JTableFixture table = frame.table(new GenericTypeMatcher<JTable>(JTable.class) {
             @Override protected boolean isMatching(JTable table) {
                return (table instanceof myTreeTable); 
             }  
        });
    }

此代码效果很好。如果我们删除5秒暂停，则找不到表，因为应用程序加载它需要几秒钟。

This code works well. If we remove the 5 seconds pause, then the table is not found because it takes some seconds to the app to load it.

我想知道是否有更干净的方式。我在ApplicationLauncher之后尝试使用robot.waitForIdle（）（我猜一旦EDT为空，一切都已加载），但它无法正常工作。

I would like to know if there is a cleaner way of doing it. I tried with robot.waitForIdle() after ApplicationLauncher (I guess once EDT is empty, everything is loaded), but it just doesn´t work.

我知道暂停可以使用某些条件作为何时停止的事件，但我不明白如何编写它，因为JavaDoc和官方文档很差。

I know pause can use some conditions as an event on when to stop, but I don´t understand how to write it since JavaDoc and official doc is poor.

• Pause.pause（WaitForComponentToShowCondition.untilIsShowing（frame.component（）））：我需要一个组件，如果我通过包装器框架它不起作用。而且我无法通过这张桌子，因为这正是我正在等待的内容。



• 我明白我应该使用ComponentFoundCondition，但我不明白！我厌倦了：

• Pause.pause(WaitForComponentToShowCondition.untilIsShowing(frame.component())) : I need a component, if I pass the wrapper frame it does not work. And I cannot pass the table because thats precisely what I am waiting for to get.

• I understand then I should probably work with ComponentFoundCondition but I dont get it! I tired with:

       ComponentMatcher matcher = new GenericTypeMatcher<JTable>(JTable.class) {
           @Override protected boolean isMatching(JTable table) {
             return (table instanceof myTreeTable); 
           }  
       };

       Pause.pause(new ComponentFoundCondition("DebugMsg", frame.robot.finder(), matcher)); 

任何帮助？

推荐答案

你可以使用 ComponentFinder 来定位组件。例如，基于问题中的匹配器：

You could use ComponentFinder to locate the component. For example, based on the matcher in the question:

final ComponentMatcher matcher = new TypeMatcher(myTreeTable.class);

Pause.pause(new Condition("Waiting for myTreeTable") {
    @Override
    public boolean test() {
        Collection<Component> list = 
                window.robot.finder().findAll(window.target, matcher);
        return list.size() > 0;
    }
 }, 5000); 

这是一个按名称查找的替代方案：

Here is an alternative with lookup by name:

final ComponentMatcher nameMatcher = new ComponentMatcher(){
    @Override
    public boolean matches(Component c) {
        return "ComponentName".equals(c.getName()) && c.isShowing();
    }
};

Pause.pause(new Condition("Waiting") {
    @Override
    public boolean test() {
        Collection<Component> list = 
                window.robot.finder().findAll(window.target, nameMatcher);
        return list.size() > 0;
    }
 }, 5000);
