Question

我想在TestNG中实现TimerTask，但它失败了。看看我的代码

  public class Task extends TimerTask {

    static int i =0;
    @Override
    public void run() {

        System.out.println(++i +" : Hi");
        if(i==40){
           System.out.println("inside run method");
           cancel();
           System.exit(0);
        }
    }

  }

上层阶级是我要实施的任务

  public class TestCount{
     private static final long DELAY = 0;
     private static final long PERIOD = 100;

    @Test
    public void test(){
       Timer timer = new Timer();
       timer.scheduleAtFixedRate(new Task(), DELAY, PERIOD);
    }
  }

输出：// 1：嗨

上面的代码，当我运行时只打印时间而不是40次。帮助我....

我想出了这个问题的解决方案。对于那些不想使用fluentwa轮询的人，可以使用我发布的这个课程。而且我没有使用THREAD或SLEEPER就实现了这一目标。该课程将视为POLLING替代方案。

public class PollingClass {
private final long MAX_WAIT_IN_SECOND = 60;
private long MAX_TIME_COUNT_IN_MILLISECOND = System.currentTimeMillis()+MAX_WAIT_IN_SECOND*1000;
private long MIN_TIME_COUNT_IN_SECOND = 10;
private static int i = 0;

WebDriver driver;
WebElement element;

public PollingClass(WebDriver driver){
    this.driver = driver;
}

public WebElement getPolling(String path){

    try{
        while(System.currentTimeMillis() < MAX_TIME_COUNT_IN_MILLISECOND)
        {
            try{
                 element  = new WebDriverWait(driver, MIN_TIME_COUNT_IN_SECOND).until(ExpectedConditions.presenceOfElementLocated(By.cssSelector(path)));

                 if(element.isDisplayed()){
                     System.out.println("element"+ ++i+" is displayed ");
                     break;
                 }  

            }catch(NoSuchElementException e){
//                  e.printStackTrace();
                continue;
            }
        }
    }catch(NoSuchElementException|TimeoutException e){
//          e.printStackTrace();
    }

    return element;
  }
}

TimerTask不适用于testng
