Question

我正在使用Eclipse在Selenium WebSriver中创建测试脚本，并且在我有父窗口的情况下遇到了障碍，我点击该窗口上的链接并打开子窗口。然后我想关闭子窗口并在父窗口上再次执行函数。

我的代码如下：

public static void daysInStockSelectContract(InternetExplorerDriver driver) {
    driver.findElement(By.xpath(".//*[@id='page-content']/table/tbody/tr[1]/td[1]/a")).click();

    for(String winHandle : driver.getWindowHandles()) {
        driver.switchTo().window(winHandle);
        driver.close();
    }
 }

当我运行上面的代码时，子窗口在父窗口关闭时保持打开状态，这与我想要的效果相反。控制台中还显示如下错误：

“线程中的异常”主“org.openqa.selenium.remote.SessionNotFoundException：session 1ff55fb6-71c9-4466-9993-32d7d9cae760”不存在“

我正在使用IE WebDriver作为我的Selenium脚本。

Subh，这是我在您发送的链接中使用的代码，但遗憾的是，该代码似乎不起作用。

public static void daysInStockSelectContract(InternetExplorerDriver driver) {
    //get the parent handle before clicking on the link
    String winHandleBefore = driver.getWindowHandle();

    driver.findElement(By.xpath(".//*[@id='page-content']/table/tbody/tr[1]/td[1]/a")).click();

    // the set will contain only the child window now. Switch to child window and close it.
    for(String winHandle : driver.getWindowHandles()) {
        driver.switchTo().window(winHandle);
    }
    driver.close();
    driver.switchTo().window(winHandleBefore);
}

Answer 1

可能没有正确切换到子窗口。

因此，＆＃39; driver.close（）＆＃39; 正在关闭父窗口，而不是子窗口。此外，由于父窗口已关闭，这意味着会话已丢失，导致错误＆＃39; SessionNotFoundException＆＃39; 。

此链接可以帮助您properly switching between windows

另一方面，只是一个建议。不要将＆＃34; driver＆＃34; 作为参数传递，为什么不将它变为静态变量。它可以很容易地被类中的所有方法及其子类访问，并且您不必费心每次都将它传递给方法.. :)

以下是您在评论中提出的代码（与上述问题无关）

public class Testing_anew {

    public static WebDriver driver;

    public static void main(String args[]) throws InterruptedException{

        driver = new FirefoxDriver();

        driver.manage().window().maximize();

        driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);

      }

    public static void testmethod(){

    driver.findElement(By.xpath("//some xpath")).click();
   }

更新了代码19/11/14

public static void daysInStockSelectContract(InternetExplorerDriver driver) {
    //get the parent handle before clicking on the link 
    String winHandleBefore = driver.getWindowHandle();

    System.out.println("Current handle is: "+winHandleBefore);

    driver.findElement(By.xpath(".//*[@id='page-content']/table/tbody/tr[1]/td[1]/a")).click();

    // Iterating through the set of window handles till the child window's handle, that is infact
    // not equal to the current window handle, is found
    for(String winHandle : driver.getWindowHandles()) {
       if(!winHandle.equals(winHandleBefore)){
                System.out.println("Child handle is: "+ winHandle);
                //Sleeping for 4 seconds for detecting Child window
                try{
                    Thread.sleep(4000);
                   }catch(InterruptedException e){
                    System.out.println("Caught exception related to sleep:"+e.getMessage());
                   }
                driver.switchTo().window(winHandle);
                break;
            }
    } 

    System.out.println("AFTER SWITCHING, Handle is: "+driver.getWindowHandle());

    driver.close();

    //Sleeping for 4 seconds for detecting Parent window
    try{
        Thread.sleep(4000);
       }catch(InterruptedException e){
        System.out.println("Caught exception related to sleep:"+e.getMessage());
       }

    driver.switchTo().window(winHandleBefore); // Switching back to parent window

     System.out.println("NOW THE CURRENT Handle is: "+driver.getWindowHandle());

     //Now perform some user action here with respect to parent window to assert that the window has switched properly


}

循环遍历windowHandles时，第一个句柄是父句柄。因此，当您说driver.close()时，父窗口将关闭。使用以下代码可以避免这种情况：

public static void daysInStockSelectContract(InternetExplorerDriver driver) {
    //get the parent handle before clicking on the link
    String parentHandle = driver.getWindowHandle();

    driver.findElement(By.xpath(".//*[@id='page-content']/table/tbody/tr[1]/td[1]/a")).click();

    //get all the window handles and assign it to a set 
    //It will include child window and parentwindow
    Set<String> windowHandles = driver.getWindowHandles();

    System.out.println("No of Window Handles: " + windowHandles.size());

    //remove the parent handle from the set
    windowHandles.remove(parentHandle);

    // the set will contain only the child window now. Switch to child window and close it.
    for(String winHandle : driver.getWindowHandles()) {

强文 driver.switchTo（）。window（winHandle）; driver.close（）; } }

如果您将大小设置为1（windowHandles的编号为1）或者获得相同的错误消息，那么该窗口可能是一个警告框。要处理警告框，您可以在单击链接后使用以下代码。

Alert alert = driver.switchTo().alert();
alert.accept();

试用此代码进行调试

public static void daysInStockSelectContract(InternetExplorerDriver driver) {
    // get the parent handle before clicking on the link
    String parentHandle = driver.getWindowHandle();
    System.out.println("ParentHandle : " + parentHandle);
    driver.findElement(
            By.xpath(".//*[@id='page-content']/table/tbody/tr[1]/td[1]/a"))
            .click();

    // get all the window handles and assign it to a set
    // It will include child window and parentwindow
    Set<String> windowHandles = driver.getWindowHandles();

    System.out.println("No of Window Handles: " + windowHandles.size());

    // remove the parent handle from the set
    windowHandles.remove(parentHandle);

    // the set will contain only the child window now. Switch to child
    // window and close it.
    for (String winHandle : driver.getWindowHandles()) {
        driver.switchTo().window(winHandle);
        System.out.println("Child Handle : " + winHandle);
        driver.close();
    }

    // get the window handles again, print the size
    windowHandles = driver.getWindowHandles();
    System.out.println("No of Window Handles: " + windowHandles.size());
    for (String winHandldes : windowHandles) {
        System.out.println("Active Window : " + winHandldes);
    }

    driver.switchTo().window(parentHandle);
}

我设法通过使用上面Subh概述的步骤解决了这个问题。特别是，确保启用保护模式＆＃39;已被禁用“安全”功能“互联网选项”选项卡＆＃39;
