硒铬驱动程序丢失窗口手柄. org.openqa.selenium.NoSuchWindowException:没有这样

Question

我正在使用以下内容，

铬驱动程序 2.41

硒服务器独立-3.10.0.jar

JDK 1.8.0_141

我使用硒在chrome中打开多个选项卡，逐个遍历每个选项卡，然后执行一些脚本。但是，我在切换窗口手柄时经常遇到错误。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org.openqa.selenium.NoSuchWindowException: no such window。

另一个奇怪的事情是，代码将运行一次。然后它会为后续测试提供错误，但是如果我们将其保持原样十分钟后，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

Answer 1

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

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

Answer 2

Public void windowHandle()
{
Set<String> allWindowHandles ==driver.getwindowHandles();
Iterator<String> iterator = allWindowHandles.iterator();
while (iterator.hasNext()) {
String ChildWindow = iterator.next();
if (!mainWindowHandle.equalsIgnoreCase(ChildWindow)) {
driver.switchTo().window(ChildWindow);
WebElement text = driver.findElement(By.id("sampleHeading"))    System.out.println("Heading of child window is " + text.getText());
}
}
