Question

我正在使用以下内容，

Chromedriver 2.41

selenium-server-standalone-3.10.0.jar

jdk 1.8.0_141

我使用硒打开chrome中的多个标签，一个一个地遍历每个标签，然后执行一些脚本。但是，在切换窗口句柄时，我经常会出错。刚要在切换窗口之前使用System.out.println(driver.getWindowHandles())，我发现窗口句柄的数量随着时间的推移而不断减少，并且得出org.openqa.selenium.NoSuchWindowException: no such window。

另一个奇怪的是，代码将运行一次。然后它将为以后的测试提供错误，但是如果我们将其保留十分钟，它将再次正常运行。

代码实现如下，

        ArrayList<String> tabs = new ArrayList<String>(driver.getWindowHandles());
        for(int j=0; j<10; j++){
            ((JavascriptExecutor) driver).executeScript("window.open('" + *siteURL* + "')");
            for(String temp : driver.getWindowHandles()){
                if(!tabs.contains(temp)){
                    driver.switchTo().window(temp);
                    tabs.add(temp);
                }
            }
        }

        tabs = new ArrayList<String>(driver.getWindowHandles());
        driver.switchTo().window(tabs.get(0));

        /*** Reload tabs to reacquire the pages- Selenium loses them if it is idle for long time
         * **/
            for (int j = 0; j < tabs.size(); j++) {
                driver.switchTo().window(tabs.get(j));
                driver.get(*siteURL*);

            }

        tabs = new ArrayList<String>(driver.getWindowHandles());
        for (int j = 0; j < tabs.size(); j++) {
          driver.switchTo().window(tabs.get(j));
         /*Perform step 1*/
        }

错误：

org.openqa.selenium.NoSuchWindowException: no such window

我遇到了同样的问题。 getWindowHandles()需要一些时间，Thread.sleep(500);可以正常工作。

public void goto2() throws InterruptedException {
    ArrayList<String> winHandles = new ArrayList<String> (driver.getWindowHandles());
    Thread.sleep(500);
    driver.switchTo().window(winHandles.get(1));
}

Selenium chromedriver丢失窗口句柄。 org.openqa.selenium.NoSuchWindowException：没有此类窗口错误
