硒:切换到新选项卡时从渲染器异常接收消息超时

Question

我正在尝试验证PDF的内容。 在我们的应用程序中，当我们单击链接时，会打开一个新选项卡，其中包含嵌入的pdf[新选项卡中没有URL]，我的任务是验证PDF的内容。

我正在尝试切换到新的 PDF 并按 Ctrl + A 和 Ctrl + c，如下所示。

ArrayList<String> tabs = new ArrayList<String> (driver.getWindowHandles());
for (String string : tabs) {
System.out.println("tab id:: "+string);
}       
driver.switchTo().window(tabs.get(1));
driver.switchTo().defaultContent();
System.out.println(driver.switchTo().window(tabs.get(0)).getTitle()); //first tab title
System.out.println(driver.switchTo().window(tabs.get(1)).getTitle()); //second tab title
String selectAll = Keys.chord(Keys.CONTROL,Keys.chord("a"));
String copy = Keys.chord(Keys.CONTROL,Keys.chord("c"));

//driver.switchTo().defaultContent();
pause(3000);
Actions action = new Actions(driver);
action.sendKeys(selectAll).perform(); 
pause(3000);
new Actions(driver).sendKeys(copy).build().perform();

但是在尝试使用新选项卡执行任何活动时，我遇到了异常。 System.out.println(driver.switchTo((.window(tabs.get(1((.getTitle(((;

下面是例外情况。

ChromeDriver 版本 = 2.35.528161 Chrome 版本 = 66.0.3359.181

任何人遇到此类问题，请让我知道解决方案。 谢谢。

Answer 1

这是一个配置问题 ChromeDriver 2.35 支持 Chrome v62-64

您需要ChromeDriver 2.39或2.38，因为您使用的是Chrome 66
